Subject Re: XPath problems in Cocoon?
Date Thu, 20 Feb 2003 11:57:14 GMT


I tried it with XPathVisualizer tool, and it gives right result.
But when I tried to run the stylesheet through the batch file using Saxon, I also
got empty result.
So I am really confused.
Maybe somebody can suggest another XPath to accomplish this?
I want to choose all a tags for which the first following tag that is not a white-space only
text
is also a tag, e.g. when there are adjacent a tags with no separate characters between them.
This seems to be not too complex XPath, and the XPath that I constructed:
//a[name(following-sibling::node()[1][not(self::text() and normalize-space())])='a']

seems to be rather intuitive, so I am really confused why it doesn't work.
Moreover, why it DOES work in XMLSpy/XPathVisualizer and DOESN"T work with Saxon/Cocoon.

I am really confused and will really appreciate any help with this issue.

Thank you very much for help.

Anna

  Hmm - I tried this same transform using Jame Clarke's
  XT program (old, but normally robust) and I got the 
  same result - 
   
  <?xml version="1.0" encoding="utf-8" ?> 
    <root />

  I am not an XSLT guru - are you sure the syntax is not
  specific to XML spy??  Have you tried with some other
  XSLT engine?

  I don't get any error message, at least not in WEB-IN/logs/error.log
  I get an xml document in the browser:
  <?xml version="1.0" encoding="utf-8" ?> 
    <root /> 

  i.e., the stylesheet was applied successfully, it just didn't match anything.
  Maybe my XPath expression is wrong, but then how comes it works in XMLSpy?

  Thanks for answering

    What type of error message do you get in the log files?

    Hi all. I am not sure that this message is related to Cocoon, so I apologize,
    if this is not appropriate here.

    I have a very simple html - test.html:
    <html>
    <head>
    <title>Test anchors</title>
    </head>
    <body>
    <p>test anchors</p>
    <a href="one.html">One</a>  <a href="two.html">Two</a>
    <div>separator</div>
    <a href="one.html">One1</a>
    <br />
    <a href="two.html">Two1</a>
    <div>separator</div>
    <a href="one.html">One2</a>
    some text
    <a href="two.html">Two2</a>
    </body>
    </html>

    I want to choose the 'a' nodes for which first following node that is not a white-space
only node is 'a' node. E.g. in the html above only the first 'a' node should be picked up.
    I wrote a very simple xsl - test.xsl:
    <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="/">
    <root>
    <xsl:for-each select="//a[name(following-sibling::node()[1][not(self::text() and normalize-space())])='a']">
    <xsl:value-of select="."/>
    </xsl:for-each>
    </root>
    </xsl:template>
    </xsl:stylesheet>

    When I apply this stylesheet on my test.html using XMLSpy's XSL Transformation Tool, I
get this xml:
    <root>One</root>, e.g. it chose correctly the first a node.
    But when I apply this stylesheet using Cocoon, I get empty <root/> as a result,
e.g. in Cocoon nothing is chosen.
    Here is my pipeline:
    <map:match pattern="testAnchors">
    <map:generate src="ub/testing/test.html" type="html"/>
    <map:transform type="xslt-saxon" src="ub/testing/test.xsl"/>
    <map:serialize type="xml"/>
    </map:match>

    Can somebody explain me what is wrong with my stylesheet and why doesn't it work using
Cocoon?

    Thank you very much for help and sorry if this is not too much related.

    Best regards,

    Anna
