  -    It implements a draft standard that is still in design.  APIs will continue to change, 
  -    with no promise of backwards compatibility.  This software contains known and unknown bugs.

  -	 <s2 title="Performance Notes"> 
  -		<p>We have done a great deal in versions 0.18 and 0.19 to improve performance. However, as these things often go, we
  -    have not yet met our goal for a 10-fold performance increase. We provide his list of what we understand the bottlenecks
  -    to be so that you may understand and, in some cases, work around them. The bottlenecks appear
  -    to be:</p> 
  -		<gloss> 
  -		  <label>Class load and JIT (Just In Time compiler)</label> 
  -		  <item>As we've added architecture to improve raw transform performance, we've 
  -		        also increased the number of classes and class instances that need loading, and 
  -		        the amount of code that needs JIT compiling.  Although we can shrink the code size 
  -		        a bit, the time required to load the processor will continue to be an issue.  The 
  -		        one thing the caller of the API can do is pre-warm the JIT by transforming 
  -		        a dummy document. For an example of this technique, see the init() method in the 
  -		        <link idref="XSLTProcessorAppletDoc"/>. During applet initialization, a dummy document
  -             is transformed, so the response time for performing "real" 
  -            transformations will be reasonable.<br/><br/></item> 
  -		   <label>Stylesheet Compilation</label>
  -		   <item>&xslt4j; now reads the stylesheet from the parser's SAX events (unless you 
  -		         give it a DOM, in which case it produces SAX events from the DOM), and builds
  -		         an internal tree structure. This structure processes the attributes, precompiles 
  -		         the XPath expressions, and does other things that can be done before it knows
  -		         about the input tree. The construction of large stylesheets is not as fast as 
  -		         we would like. We have been focusing on the transformation itself, and will 
  -		         have to concentrate on optimizing the stylesheet compilation down the road a bit.
  -		        <br/><br/></item>
  -		   <label>The DOM</label>
  -		   <item>DOM nodes are big.  Every node, including attribute nodes and whitespace nodes, 
  -		        have a next, previous, parent, first child, last child, ownerDocument, name, value, userData,
  -		        and a few internal flags. So building the input DOM can take a lot of memory 
  -		        management. We are working on ways to get around this when &xslt4j; builds 
  -		        the input tree, while still maintaining our DOM input architecture.<br/><br/></item>
  -		   <label>Union Sorting in Document Order</label>
  -		   <item>XSLT has to return nodes in document order. Determining document order from 
  -		         a pure DOM is difficult. We have developed a method to determine the order
  -		         that is pretty good, but it is not as fast as simply determining document order 
  -		         based on a integer.  Also, the collation method of combining two node lists 
  -		         is not as effecient as it needs to be, simply because we haven't had time to 
  -		         address it yet (the issues are more complex than was first apparent).  The net 
  -		         of this is that union expressions aren't scalable to large node sets.  For instance,
  -		         we have one user who has a large document with 3800 elements right under the 
  -		         root node, and they apply a standard 
  -		         select="*|@*|comment()|processing-instruction()|text()" expression to these 
  -		         nodes. The 3800 elements happen to have 3800 whitespace nodes interleafed 
  -		         between them, and the union selection has to create a nodelist of 3800 elements 
  -		         and 3800 whitespace nodes, and combine them, testing for document order as 
  -		         it goes.  As a result, the processing takes forever.  We're working on ways 
  -		         to fix this, but, the answer for this user was to not do the union selection 
  -		         at the top level (they didn't care about the whitespace nodes anyway).
  -		        <br/><br/></item>
  -		     <label>Selects in Large Documents</label>
  -		     <item>&xslt4j; currently builds no inverted indexes for the input document, and 
  -		           does not take advantage of DTD structures to optimize, and otherwise does 
  -		           no special magic to locate nodes other than try to implement efficient 
  -		           algorithms.  While inverted indexes and taking advantage of DTD structures 
  -		           are on our list for options, users should be aware that patterns such as 
  -		           '//foo' at the top of the tree can be expensive.
  -		        <br/><br/></item>
  -		     <label>xsl:number and xsl:sort</label>
  -		     <item>Both sorting and numbering are not as efficient as they could be.

  -      <ul>
  -   		     <li>&xslt4j; is thread-safe with an instance per thread.  You can not run 
  -           the same instance in multiple threads.</li>
  -		       <li>&xslt4j; contains a DTD for XSL when used for HTML. (Thanks be to
  -           Henrique M. Holschuh for this). This DTD should not be used for run-time
  -           production when performance is a concern, but is useful during the development
  -           stages. It is used in the readme XSL.<br/><br/></li> 
  -        <li>
  -        The rule for whitespace that can be stripped is as follows:<br/>
  -        If a text node contains whitespace followed by a non-whitespace 
  -        character followed by whitespace, none of the whitespace is ever 
  -        stripped.  If a text node is all whitespace, and does not have 
  -        siblings that are character data, it should be stripped.  A 
  -        CDATA section is interpreted as character data.<br/><br/>
  -        </li>
  -        <li>
  -        Be aware that select arguments for variables, or arguments passed through the 
  -        command line via the -PARAM switch, are expressions, not strings.  So to set 
  -        a variable to a string you need to do:<br/>
  -        <code>
  -        <![CDATA[<xsl:variable name="ExpressionTest" 
  -                               select="'A test for xsl:constant and xsl:value-of'"/>]]>
  -        </code><br/>
  -        Notice the extra single quotes (').<br/><br/>
  -        </li>
  -        <li>
  -        If you're using an XSL stylesheet with a DTD, attributes typed as IDs will 
  -        have a problem when you try and put an attribute template into them.  Just 
  -        something to watch out for.  We don't really have a solution for this, 
  -        except that you probably can't type literal result element attributes as 
  -        IDs for the XSL stylesheet.<br/><br/>
  -        </li>

  -		  <s2 title="Redirect Extension (Multiple Output Docs)"> 
  -      <p>&xslt4j; has a built in extension to let you produce multiple output documents 
  -      from a single stylesheet.  The extension is limited right now to producing 
  -      files, when the output method is "xml", "html", or "text". See <resource-ref

  +     <p>The &xslt4j; build is in xalan.jar. The &xslt4j; source code tree is in the src directory.
  +     If you want to rebuild xalan.jar, you can do the following:</p>
  +     <ol>
  +       <li>Set up GNU or the equivalent build environment on your workstation.<br/><br/>
  +       If you are running Windows 95/98/NT, you can use the Cygwin port of GNU. Be sure to put the
  +       appropriate Cygwin bin directory at the beginning of your system path. For information about
  +       Cygwin, see <jump href="http://www.sourceware.cygnus.com/cygwin/">Cygwin</jump>.<br/><br/></li>
  +       <li>Place <resource-ref idref="xerces-used"/> xerces.jar in the Java classpath.<br/><br/></li>
  +       <li>If you are working in Windows, set MAKE_MODE as follows:<br/><br/>
  +       <code>set MAKE_MODE=UNIX</code><br/><br/></li>
  +       <li>Run the make file in the &xslt4j; root directory:<br/><br/>
  +       <code>make build</code><br/><br/></li>
  +     </ol>
  +     <p>If you want to do the build without the GNU build environment, keep the following in mind:</p>
  +     <ul>
  +     <li>Set the class path to include the src directory, xerces.jar, bsf.jar, and bsfengines.jar.</li>
  +     <li>Use javac to compile all the .java files in the src tree. </li>
  +     <li>Use the Sun jar utility to store the resulting .class files in xalan.jar</li>
  +     </ul>
  +   </s3><anchor name="samples"/>
  +   <s3 title="Rebuilding a sample application">
  +   <p>If you modify a sample and want to recompile it, you can run javac in the directory containing the
  +   example. Be sure xalan.jar and xerces.jar are on the class path. To recompile (and run!) the class files in the
  +   Servlet subdirectory, the javax.servlet and javax.servlet.http packages must also be on the class path. Sun
  +   distributes these packages in the JSWDK 1.0.1 servlet.jar file.</p> 
  +   <p>After recompiling a sample, you can use the Sun jar utility to place your  new .class files in
  +    xalansamples.jar.</p>
  +   </s3><anchor name="doc"/>
  +   <s3 title="Rebuilding the &xslt4j; documentation">
  +     <p>&xslt4j; includes a number of XML source files, XSL stylesheets, document type definition (DTD)
  +      files, entity relationship (ENT) files, graphics, and a JavaScript file that provide the input for the Xalan
  +      HTML User's Guide, and the overview and package-level documents used during the generation of Javadoc.</p>
  +     <p>To generate the Xalan HTML User's Guide, run the Xalan make file in the Xalan xdocs directory:<br/><br/>
  +     <code>make stylebook</code></p>
  +     <p>To generate Xalan API documentation, set up the make file to use the Javadoc tool in the Java JDK 1.2.2 bin 
  +     directory.</p>
  +     <p>Do the following:</p>
  +       <ol>
  +         <li>Put the Java JDK 1.2.2 bin directory on your path (in front of any JDK 1.1.x bin 
  +         directory that appears on the path).<br/><br/></li>
  +         <li>In the Xalan docs directory, run the Xalan make file as follows:<br/><br/>
  +         <code>make javadoc</code><br/><br/></li>
  +      </ol>
  +      <p>If you want to rebuild the documentation without using the GNU build environment, keep the following in
  +       mind:</p>
  +       <ul>
  +       <li>Be sure stylebook-1.0-b1.jar, xalan.jar, bsf.jar, bsfengines.jar, and xerces.jar are on the class
  +       path.<br/><br/></li>
  +       <li>To build doc in a build/docs subdirectory, run StyleBook from the xdocs directory as follows:<br/><br/>
  +<code>java org.apache.stylebook.StyleBook "targetDirectory=../build/docs/" sources/xalanLocal.xml style</code>
  +       <br/><br/></li>
  +       <li>To build the html source files that javadoc needs for top-level and package-level documentation, run
  +        StyleBook from the xdocs directory as follows:<br/><br/>
  +        <code>java org.apache.stylebook.StyleBook "loaderConfig=sbk:/style/loaderjdoc.xml" targetDirectory=../src sources/javadocPackages.xml style</code><br/><br/></li>
  +        <li>Before you run javadoc, make sure the following directory structure exists under the Xalan root
  +         directory: build/docs/apidocs.<br/><br/></li>
  +       <li>To build the API documentation, run the JDK 1.2.2 javadoc tool from the xdocs directory:<br/><br/>

     <s2 title="Introduction">
  -    <p>&xslt4j; (named after a rare musical instrument) provides high- 
  -      performance XSL stylesheet processing. &xslt4j; fully implements the W3C 
  -      XSLT recommendation. The stylesheet processor is feature rich and 
  -      robust. 
  -    </p>
  -    <p>XSL is a language for expressing stylesheets and other types of transformations. 
  -		It consists of two parts:</p> 
  -		  <ol> 
  -		    <li>XLST, a language for transforming XML documents into other XML documents,
  -        HTML documents, or other document types. This part of the language includes the XSL
  -        Transformation vocabulary and XPath, a language for addressing parts of an XML document. 
  -        XPath is designed to be used by both XSLT and XPointer.<br/><br/></li>
  -		    <li>An XML vocabulary for specifying formatting semantics (called <ref>Formatting
  -        Objects</ref>).<br/><br/></li> 
  -			</ol> 
  -
  -		  <p>&xslt4j; implements the first part of XSL, the <resource-ref idref="xsl-draft-used"/>.
  -       An XSLT stylesheet specifies the transformation that may be performed with a range of XML 
  -       documents by describing how to transform such a tree of nodes into another XML tree of
  -       nodes.</p>
  -       <note>The XSLT stylesheet may include cascading style sheets (CSS) in the result.</note>
  -       <p>In the following example, the foo.xsl stylesheet is used to transform foo.xml into foo.out:</p>
  -       <p>foo.xml:</p>
  -        <source>
  -&lt;?xml version="1.0"?>
  -&lt;doc>Hello&lt;/doc>
  -        </source>
  +    <p>&xslt4j; (named after a rare musical instrument) fully implements the <resource-ref idref="xsl-draft-used"/>. 
  +    XSLT is the first part of the XSL stylesheet language for XML. It includes the XSL Transformation vocabulary and the
  +    XML Path language (XPath), a language for addressing parts of XML documents. For links to background materials, 
  +    discussion groups, frequently asked questions, and tutorials on XSLT, see <link anchor="uptospeed">Getting up
  +    to speed with XSLT</link>.</p> 
  +    <note>XSL also includes a formatting vocabulary, which is still under design and is not part of &xslt4j;. 
  +    For more information, see <jump href="http://www.w3.org/TR/xsl/">W3C XSL Working Draft</jump> and the <jump
  +    href="http://xml.apache.org/fop">Apache XML FOP (Formatting Objects Project)</jump>.</note>
  +    <p>You use XSLT to compose stylesheets (themselves XML documents) for transforming XML documents into other XML
  +    documents, HTML documents, or other document types. In structural terms, an XSLT stylesheet specifies the transformation
  +    of one tree of nodes (the XML input) into another tree of nodes (the output or transformation result).</p>
  +    <note>The XSLT stylesheet may include cascading style sheets (CSS) in the result.</note> 
  +    <p>In the following example, the foo.xsl stylesheet is used to transform foo.xml into foo.out:</p>
  +    <p>foo.xml:</p>
  +        <source>&lt;?xml version="1.0"?>
  +&lt;doc>Hello&lt;/doc></source>
           <p>foo.xsl:</p>
  -        <source>
  -&lt;?xml version="1.0"?> 
  +        <source>&lt;?xml version="1.0"?> 
   &lt;xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
   &lt;xsl:template match="doc">
   &lt;out>&lt;xsl:value-of select="."/>&lt;/out>
   &lt;/xsl:template>
   &lt;/xsl:stylesheet></source>
  -      <p>foo.out:</p><source>
  -&lt;out>Hello&lt;/out></source>
  -		  <p>By default, &xslt4j; uses &xml4j; 
  -      to parse input XML documents and XSL stylesheets, but it can be adapted to work with 
  -      other DOM-producing mechanisms.</p>
  -      <p>During the course of a transformation, &xslt4j; produces SAX events, 
  -      an output DOM, or an XML result document based on the transformations specified in the 
  -      XSL stylesheet.</p>
  -      </s2>
  +<p>foo.out:</p>
  +<source>&lt;out>Hello&lt;/out></source>
  +<p>By default, &xslt4j; uses a high-performance <link idref="dtm">Document Table Model (DTM)</link> to parse the input -- XML documents and XSL stylesheets, but it can be set to use the &xml4j; XML parser, and it can be adapted to work with other DOM-producing mechanisms and SAX document handlers. The input may appear in the form of a file, a character stream, a byte stream, a DOM, or a SAX input stream.</p>
  +<p>&xslt4j; performs the transformations specified in the XSL stylesheet and produces a document file, a character
  + stream, a byte stream, a DOM, or a series of SAX events, as you specify when you set up the transformation.</p>

    // Perform the transformation.
    processor.process(xmlSource, xslSheet, xmlResult);
   }</source>
  <p>For an online example, see <link idref="samples" anchor="simpletransform">SimpleTransform</link>.</p>
  <p>You can perform this same operation from the <link idref="commandline">command line</link>. For example:</p>
  <p><code>java org.apache.xalan.xslt.Process -in foo.xml -xsl foo.xsl -out output.xml</code></p>
  </s2><anchor name="streams"/>
  <s2 title="Using data streams in place of files">
  <p>The context in which you perform a transformation may call for input in the form of a character stream, byte stream, or SAX input stream, and output in the form of a character stream, byte stream, or SAX document handler. Suppose, for example, you want to output a stream of bytes for further processing:</p>
  <source>import org.apache.xalan.xslt.*;
  ...
  java.io.OutputStream byteStream = new java.io.OutputStream();
  XSLTRegultTarget out = new XSLTResultTarget(byteStream)
  // Do the transformation...
  // Work with the OutputStream...</source>
  
  </s2><anchor name="params"/>
  <s2 title="Setting stylesheet parameters">
  <p>An XSL stylesheet can include parameters that get set at run time when a transformation takes place. When we generate the HTML documents that make up the Xalan doc set, for example, we send the stylesheet an id parameter along with each XML source document. The id identifies that document and enables the stylesheet to integrate it into the overall doc set.</p>
  <p>To set a stylesheet parameter, use the XSLTProcessor setStylesheetParam(String paramName, String paramExpr) method. paramExpr is an XPath expression, so if the parameter is a String, enclose it in single quotes to make it a String expression.</p>
  <p>You can also use setStylesheetParam(String key, XObject value). This option is useful when you are working with the XPath API. For example, you could use the XObject returned by an Xpath function to set a parameter.</p>
  <p>From the <link idref="commandline">command line</link>, include a -param argument. For example:</p>
  <p><code>java org.apache.xalan.xsltProcess -in foo.xml -xsl foo.xsl -param 'boo'</code></p>
  </s2><anchor name="compiled"/>
  <s2 title="Compiling stylesheets">
  <p>A <resource-ref idref="StylesheetRootDoc"/> object is a binary representation of a stylesheet that adds efficiency to the performance of repeated transformations and supports threadsafe concurrent access by multiple clients. If, for example, you are setting up a servlet to perform transformations, you can improve performance by compiling any stylesheets the servlet repeatedly uses.</p>
  <p>To compile a stylesheet, use one of the the <resource-ref idref="XSLTProcessorDoc"/> processStylesheet methods. This operation also sets the XSLTProcessor Stylesheet property. In the interest of clarity, you may want to explicitly set that property. When you call the process method, include a null for the "uncompiled" stylesheet parameter so XLTProcessor uses the compiled stylesheet. For example:</p>
  <source>import org.apache.xalan.xslt.*;
  ...
  XSLTProcessor processor = XSLTProcessorFactory.getProcessor();
  StylesheetRoot style = processor.processStylesheet(new XSLTInputSource("foo.xsl"));
  processor.setStylesheet(style); // Good form!
  ...
  processor.process(new XSLTInputSource("foo.xml"),
                    null, // Use the Stylesheet property setting.
                    new XSLTOutputTarget("foo.out"));</source>
  <p>Alternative: For convenience, StylesheetRoot has its own process method, so another way to do the preceding is as follows:</p>
  <source>import org.apache.xalan.xslt.*;
  ..
  XSLTProcessor processor = XSLTProcessorFactory.getProcessor();
  StylesheetRoot style = processor.processStylesheet(new XSLTInputSource("foo.xsl"));
  ...
  style.process(new XSLTInputSource("foo.xml"), new XSLTOutputTarget("foo.out"));</source>
  <p>If you want to use the XSLTProcessor as a SAX document handler, you must provide the processor a compiled stylesheet. See <link anchor="sax">Generating and Responding to SAX events</link>.</p>
  </s2><anchor name="dom-in"/>
  <s2 title="Processing DOM input">
  <p>The XML source and XSL stylesheet for a transformation may appear in the form of a DOM Node. To perform transformations with DOM input, you cannot use the default high-performance DTM liaison and parser. <link idref="dtm">DTM (Document Table model)</link> uses a table of integers to represent a DOM, thus avoiding much of the overhead of creating and manipulating actual DOM nodes, which often involve a large number of Java objects. If you are processing DOM input, you must use a DOM parser, such as the Xerces DOM parser. When you create the XSLTProcessor for the transformation, you must specify that it is to use the Liaison for such a DOM parser.</p>
  <p>The following code fragments illustrate the procedure for working with DOM input:</p>
  <source>import org.apache.xerces.parsers.DOMParser;
  import org.w3c.dom.Document;
  import org.apache.xalan.xpath.xdom.XercesLiaison;
  import org.apache.xalan.xslt.*;
  ...
  // Just in case you want to produce your own DOM input...
  DOMParser parser = new DOMParser();
  parser.parse("foo.xml");
  Document in = parser.getDocument();
  XSLTInputSource xmlID = new XSLTInputSource(in);
  
  // Set up the XSLTProcessor to use XercesLiaison.
  XSLTProcessor xsltProc = XSLTProcessorFactory.getProcessor
                   (new org.apache.xalan.xpath.xdom.XercesLiaison())
  // or you can use XSLTProcessorFactory.getProcessorUsingLiaisonName
  //                ("org.apache.xalan.xpath.xdom.XercesLiaison")
  ...
  // Perform the transformation.</source>
  </s2><anchor name="dom-out"/>
  <s2 title="Producing DOM output">
  <p>To produce a DOM Node as your transformation output, use a new Node to create the XSLTResultTarget for the transformation. Then when you perform the transformation, the result is output as a DOM Node. For example:</p>
  <source>import org.w3.dom.Document;
  import org.apache.xalan.xslt.*;
  ...
  XSLTProcessor xsltProc = XSLTProcessorFactory.getProcessor();
  org.w3c.dom.Document out = new org.apache.xerces.dom.DocumentImpl();
  XSLTResultTarget resultTarget = new XSLTResultTarget(out);
  processor.process(new XSLTInputSource("foo.xml"),
                    new XSLTInputSource("foo.xsl"),
                    resultTarget);</source>
  <p>The XSLTResultTarget object (resultTarget) now contains a Node. For a working example, see <link idref="samples" anchor="transformtodom">TransformToDom</link>.</p>
  </s2><anchor name="sax"/>
  <s2 title="Generating and responding to SAX events">
  <p>To set up a transformation to generate SAX events, set the DocumentHandler property of the XSLTResultTarget object. The transformation consumer can then respond to these events as they occur, rather than waiting (as the consumer of a DOM must) for the complete result tree.</p>
  <p>This example sends the output to System.out.</p>
  <source>import org.apache.xalan.xslt.XSLTProcessor;
  import org.apache.xalan.xslt.XSLTInputSource;
  import org.apache.xalan.xslt.XSLTResultTarget;
  import org.apache.xalan.xslt.XSLTProcessorFactory;
  import org.apache.xalan.xslt.StylesheetRoot;
  
  public class TransformToSax
  {
  	public static void main(String[] args)
      throws java.io.IOException,
             java.net.MalformedURLException,
             org.xml.sax.SAXException
  	{
      XSLTProcessor processor = XSLTProcessorFactory.getProcessor();
  
      // Set the processor to use a compiled stylesheet.
      // The stylesheet provides access to a SAX DocumentHandler,
      // passing it the stylesheet xsl:output settings.
      StylesheetRoot stylesheet = processor.processStylesheet("foo.xsl");
      // This property was just set implicitly, but for good form...
      processor.setStylesheet(stylesheet);
      // In this case, send the output to System.out.
      org.xml.sax.DocumentHandler dh = stylesheet.getSAXSerializer(System.out);
  
      // Use the DocumentHandler to construct an XSLTResultTarget object.
      XSLTResultTarget saxResult = new XSLTResultTarget(dh);
  
      // Perform the transformation. The stylesheet parameter is null, so
      // the processor uses the compiled stylesheet identified by its 
      // Stylesheet property setting.
      processor.process(new XSLTInputSource("foo.xml"), null, saxResult);
  	}
  }</source>
  <p>XSLTProcessor also has a DocumentHandler property (in fact, XSLTProcessor extends DocumentHandler). By setting this property, you instruct the processor to process a sequence of SAX events. The processor needs a compiled stylesheet to perform this transformation.</p>
  <p>The following example uses the output of one transformation as the input for a second transformation. It does this by using two SAX DocumentHandlers to pipe SAX events from the first transformation to the second.</p>
  <source>import org.apache.xalan.xslt.*;
  
  public class ChainTransforms
  {
  	public static void main(String[] args)
      throws java.io.IOException,
             java.net.MalformedURLException,

      // DocumentHandler properties so this processor uses the
      // 2nd stylesheet and processes SAX events (output from the

      XSLTProcessor processor2 = XSLTProcessorFactory.getProcessor();
      StylesheetRoot stylesheet2 = processor2.processStylesheet("foo2.xsl");
      processor2.setStylesheet(stylesheet2);
      org.xml.sax.DocumentHandler dh = stylesheet2.getSAXSerializer(System.out);
      processor2.setDocumentHandler(dh);
  
      // Set up the 1st transform to produce a series of SAX events, and
      // to pass these events to the processor for the 2nd transform.
      // To accomplish this, create an XSLTResultTarget object for the
      // 1st transform, and use the processor for the 2nd transform to set
      // the XSLTResultTarget DocumentHandler property.
      XSLTResultTarget intermedResult = new XSLTResultTarget();
      intermedResult.setDocumentHandler(processor2);
  
      // Perform the 1st transform, which produces a series of
      // SAX events that are in turn processed by the processor2 DocumentHandler
      // in conjunction with stylesheet2, sending the output to System.out.
      processor1.process(new XSLTInputSource("foo.xml"),
                         new XSLTInputSource("foo.xsl"),
                         intermedResult);

  <s2 title="Working with XPath expressions">
  <p>XSL stylesheets use XPath expressions to select nodes, specify conditions, and generate text for the result tree. XPath provides an API that you can call directly.

  	  <s2 title="Samples to help you get started">
      <p>Each of the subdirectories in the &xslt4j; samples directory contains the source files for one or more
       sample applications. The class files for all the samples are in xalansamples.jar, so to run the samples, 
       you should place xalansamples.jar on the system class path.</p>
       <p>With most of the samples, you can use the following procedure:</p>
       <ol>
       <li>Be sure xalan.jar, xalansamples.jar, and xerces.jar are on the system class path. For the extension
        examples, bsf.jar, bsfengines.jar, and (for the JavaScript extensions) js.jar must also be on the class
        path.</li>
       <li>Be sure java.exe is on your path.</li>
       <li>Go to the samples subdirectory containing the sample (use the DOS shell if you are running Windows).</li>
       <li>Run the sample from the command line (as indicated below)</li>
      <li>Examine the application source files. You may also want to modify the source files. Remember that if you
       modify a java file, you must recompile the class and place it on the class path before you can run the
       modified application.</li>
       </ol>      
      <p>The basic command line for running most of the samples is </p> 
      <p><code>java <ref>classname args</ref></code></p>
      <p>where <ref>classname</ref> is the classname and <ref>args</ref> are the arguments, if any. As described in
       the following sections, some samples take no arguments. The samples in UseStylesheetParam and ApplyXPath take
       additional arguments. The samples in extensions use the &xslt4j; <link idref="commandline">command-line
       utility</link>, so they take arguments for the XML source file and the XSL stylesheet.</p>
    	</s2><anchor name="simpletransform"/>
      <s2 title="SimpleTransform">
      <p>What it does: The SimpleTransform class uses the foo.xsl stylesheet to transform foo.xml, and prints the
       output to System.out.</p>
      <p>You can run it from the SimpleTransform subdirectory with</p>
      <p><code>java SimpleTransform</code></p>
      </s2><anchor name="transformtodom"/>
      <s2 title="TransformToDom">
      <p>What it does: The TransformToDom class uses the foo.xsl stylesheet to transform foo.xml, produces an output
       DOM, and traverses the DOM, printing the traversal to System.out. In contrast to SimpleTransform,
        TransformToDom illustrates the procedure for creating an output DOM that is available for further
        processing.</p>
     <p>You can run it from the TransformToDom subdirectory with</p>
      <p><code>java TransformToDom</code></p>
      </s2><anchor name="usestylesheetparam"/>
      <s2 title="UseStylesheetParam">
        <p>What it does: The UseStyleSheetParam class uses foo.xsl and a stylesheet parameter to transform foo.xml,

      <p>Run this sample from the UseStylesheetParam subdirectory with</p> 
      <p><code>java UseStylesheetParam <ref>param</ref></code></p>

      <s2 title="ApplyXPath">
      <p>What it does: The ApplyXPath class executes an XPath expression against an XML document and returns
       information about the route it takes and the nodes (if any) it finds.</p>
       <note>You can use this sample as an aid when you want to find out what a given XPath expression returns from a
       given XML file. Keep in mind that the context node for the XPath expression is the document root.</note>
      <p>Run this sample from the ApplyXPath subdirectory with</p> 
      <p><code>java ApplyXPath <ref>XMLFile XPathExpression</ref></code></p>
      <p>where <ref>XMLFile</ref> is an XML source file and <ref>XPathExpression</ref> is an XPath expression to
       apply to that file. The ApplyXPath subdirectory contains an XML file named foo.xml, so you can try command
       lines like</p>
      <p><code>java ApplyXPath foo.xml /</code></p>
      <p>and</p>
      <p><code>java ApplyXPath foo.xml /doc/name/@first</code></p>

      <s2 title="Pipe">
      <p>What it does: The Pipe class uses the output of the first transformation as input to a second
       transformation.</p>
       <p>The first transformation produces a sequence of SAX events which the second transformation processes with
        its own stylesheet. The consumer of SAX output can respond to these events as they occur, rather than waiting
         for the entire result tree to be constructed (as the DOM consumer must do).</p>
      <p>Run this sample from the Pipe subdirectory with</p> 
      <p><code>java Pipe</code></p>

      <s2 title="Extensions">
      <p>The extensions subdirectory contains four samples with &xslt4j; extensions. Two of the samples use
       extensions implemented in JavaScript, and two of the samples use extensions implemented in Java. All of
       the samples are documented in <link idref="extensions">Extensions</link>.</p>
       <p>To run these examples, you must place bsf.jar and bsfengines.jar (distributed with &xslt4j;), and js.jar
       (available from http://www.mozilla.org/rhino) on the class path. You do not need js.jar
       on the class path for the samples that use Java extensions. </p>
       <p>Use java.org.apache.xalan.xslt.Process, the &xslt4j; command-line utility, to run these samples from
        the <link idref="commandline">command line</link>. The command line must include an -in flag with the 
        XML source and an -xsl flag with the XSL stylesheet. If you want the output to be printed to a file, rather
        than to the screen, add an -out flag with the output file name.</p>
        <p>Run these samples from the extensions directory as follows (each of the following is a single command

      <p>How to run it:</p>
      <ol>
        <li>Configure your application server (Websphere or JServ, for example) so it can find the classes (in

  <s2 title="Downloading what you need">
  <p>To use Xalan, you need the following:</p>
  <ul>
  <li>The JDK or JRE 1.1.6 or later</li>
  <li>xalan.jar</li>
  <li>xerces.jar</li>
  </ul>
  <p>You can get the Sun JDK or JRE from <jump href="http://www.java.sun.com">java.sun.com</jump>. Download the latest release of Xalan and Xerces-java from <jump href="http://xml.apache.org/dist/">xml.apache.org</jump>. Check the <link idref="readme" anchor="status">version release notes</link> to verify that you are using the correct version of Xerces. <em>Important</em> You may experience unpredicable difficulties and anomalies if your &xslt4j; and &xml4j; builds are not in synch. You can use &xslt4j; with some other XML parser, but it is up to you to implement a liaison to that parser. Your liaison class should extend org.apache.xalan.xpath.xml.XMLParserLiaisonDefault and implement org.apache.xalan.xpath.XPathSupport.</p>
  <note>You may also download the latest releases of LotusXSL and the XML Parser for Java from <jump href="http://www.alphaworks.ibm.com/tech/LotusXSL">alphaWorks</jump>. LotusXSL and the XML Parser for Java are Xalan and Xerces-java respectively, along with additional features and with wrappers to support the core API in place on alphaWorks before the first releases of Xalan and Xerces-java on xml.apache.org in November 1999. The alphaWorks LotusXSL release also provides continued support for earlier alphaWorks releases of the XML4J DOM and TXDOM parsers.</note>
  <p>If you plan to run <link idref="extensions">XSLT extensions</link>. you need bsf.jar and bsfengines.jar, both of which are included in the Xalan distribution. If you plan to run XSLT extensions implemented in JavaScript or another scripting language, you will need one or more additional files as indicated in <link idref="extensions" anchor="supported-lang">extensions language requirements</link>.</p>
  </s2><anchor name="classpath"/>
  <s2 title="Setting up the system class path">
  <p>At the very minimum, you must include xalan.jar and xerces.jar on the system class path. To run the sample applications, include xalansamples.jar To run extensions, include bsf.jar and bsfengines.jar. All these JAR files are distributed with &xslt4j;. For extensions implemented in JavaScript or another scripting language, see <link idref="extensions" anchor="supported-lang">extensions language requirements</link> to identify any additional JAR files you must place on the class path and where you can get them.</p>
  <p>If you are using JDK or JRE 1.1.x (at least 1.1.7, please), also include classes.zip on the class path.</p>
  </s2><anchor name="samples"/>
  <s2 title="Trying out the samples">
  <p>The Xalan distribution includes a number of basic sample applications. These samples are easy to run, and you can review the source files -- all of which are brief -- to see just how they work.</p>
  <p>To run the samples, do the following:</p>
  <ol>
  <li>Set up your class path (see above), including xalansamples.jar.</li>
  <li>Be sure java.exe is on your path.</li>
  <li>Go to the samples subdirectory containing the sample (use the DOS shell if you are running Windows).</li>
  <li>Run the sample from the command line.</li>
  <li>Examine the application source files.</li>
  </ol>
  <p>For example, go to the SimpleTransformation subdirectory and issue the following command:</p>
  <p><code>java SimpleTransformation</code></p>
  <p>The sample displays the transformation result on the screen. To see how the example works, examine the source files: foo.xml, foo.xsl, and SimpleTransformation.java.</p>
  <p>The extensions examples require additional JAR files on the class path, and the procedure for running the sample applet and sample servlet is different. For more information about all the samples, see <link idref="samples">&xslt4j; Samples</link>.</p>
  </s2><anchor name="commandline"/>
  <s2 title="Performing your own transformations from the command line">
  <p>java.org.apache.xalan.xslt.Process provides a basic utility for performing transformations from the command line. You use this utility, for example, to run the extensions samples. The command-line for the most standard of
   transformations is as follows:</p>
  <p><code>java org.apache.xalan.xslt.Process -in <ref>xmlSource</ref></code><br/>
  <code>&nbsp;&nbsp;&nbsp;&nbsp;-xsl <ref>stylesheet</ref> -out <ref>outputfile</ref></code></p>
  <p>where <ref>xmlSource</ref> is the XML source file name, <ref>stylesheet</ref> is the XSL stylesheet file name, and <ref>outputfile</ref> is the output file name.</p>
  <p>If you want the output to be displayed on the screen, simply omit the -out flag and argument.</p>
  <p>You can use this utility to try out XSL stylesheets you have written, to make sure they do what you expect with the XML source files they are designed to transform. The utility provides useful messages if the source file or stylesheet is not well-formed. If you include a DOCTYPE statement in your XML source files and include the -validate flag on the command line, the utility will also let you know whether the XML document is valid (conforms to that DOCTYPE). For more information, see <link idref="commandline">Command-Line Utility</link>.</p>
  </s2><anchor name="java-apps"/>
  <s2 title="Setting up your own Java applications">
  <p>You can start by using your own XML source files and XSL stylesheets with the sample applications, which illustrate a number of the <link anchor="usage-patterns">basic usage patterns</link>.</p>
  <p>If you modify a java source file, be sure to compile the class and place it on the system class path. Here are some basic points to keep in mind as you are setting up transformations:</p>
  <ul>
  <li>Use one of the <resource-ref idref="XSLTProcessorFactoryDoc"/> static getProcessor methods to set up an <resource-ref idref="XSLTProcessorDoc"/>. <br/><br/>By default, the XSLTProcessor uses the <resource-ref idref="DTMLiaisonDoc"/> and the high-performance <link idref="dtm"> Document Table Model (DTM)</link>"pseudo" DOM parser to process the input.  If your input is a DOM node (rather than a file, character stream, byte stream, or SAX input stream), you must use a "standard" DOM liaison and parser, such as the <resource-ref idref="XercesLiaisonDoc"/> and the Xerces DOM parser. For an example, see <link anchor="dom-in">Processing DOM input</link>.<br/><br/></li>
  <li>Set up <resource-ref idref="XSLTInputSourceDoc"/> objects for the XML input and XSL stylesheet. You can use a file name or URL, character streams, byte streams, or SAX input stream to instantiate an XSLTInputSource object.<br/><br/>
  If the XML document contains a stylesheet Processing Instruction (PI), you do not need to create a separate
  XSLTInputSource object for an XSL stylesheet.<br/><br/></li>
  <li>For improved performance with a series of transformations, use the XSLTProcessor processStylesheet method to compile the XSL stylesheet (the result is a <resource-ref idref="StylesheetRootDoc"/>.<br/><br/>
  This is also useful when you need to get information from the stylesheet before the tranformation occurs, for
  instance, when you need to find out the output encoding in order to construct the right kind of Writer.
  You must also compile the stylesheet if you are using the XSLTProcessor as a SAX document handler.<br/><br/></li>
  <li>Set up an <resource-ref idref="XSLTResultTargetDoc"/> for the transformation output. You can use a file name or URL, character stream, byte stream, or SAX document handler to instantiate an XSLTOutputTarget object.<br/><br/></li>
  <li>Use the XSLTProcessor (or, in some cases, the <link idref="StylesheetRootDoc"/>) process method to perform the transformation.<br/><br/>
  &xslt4j; is thread-safe for one instance per thread. If you are using the same instance of XSLTProcessor to perform
  more than one transformation, call the reset method between transformations.</li>
  </ul>
