Subject [XalanJ2][C2] javax.xml.transform interfaces - 2 Problems.
Date Mon, 06 Nov 2000 15:40:55 GMT
Scott,

There are two problems.

Problem #1:
There is a problem with the attached sample (simple.xsp and xsp.xsl). It works well with the
old
jar and has problems with the new changes when i run using the following command-line. 

"java org.apache.xalan.xslt.Process -IN simple.xsp -XSL xsp.xsl"

The problem is that the following template does not work. which drastically reduces the output
XML.

...
...
        <!-- Process only 1st non-XSP element as generated root -->
        <xsl:call-template name="process-first-element">
          <xsl:with-param
                          name="content"
                          select="*[not(starts-with(name(.), 'xsp:'))]"/>
        </xsl:call-template>
...
...
  <xsl:template name="process-first-element">
    <xsl:param name="content"/>
    <xsl:apply-templates select="$content[1]"/>
  </xsl:template>
...
...

Problem #2: Need to check for Null's in Expression.java, Function warn().

  public void warn(XPathContext xctxt, int msg, Object[] args)
          throws org.xml.sax.SAXException
  {
    java.lang.String fmsg = XSLMessages.createXPATHWarning(msg, args);
    if(xctxt!=null && xctxt.getPrimaryReader()!=null)
    {
        ErrorHandler eh = xctxt.getPrimaryReader().getErrorHandler();
        if (null != eh)
        {
          // TO DO: Need to get stylesheet Locator from here.
          eh.warning(new SAXParseException(fmsg, (SAXSourceLocator)xctxt.getSAXLocator()));
        }
    }
  }

Thanks,
dims
