You're missing a closing "}" in the forEach:

How embarassing. I'd tried it in three different situations, and must 
have copied the code each time with the error :-( Next problem was I was 
looking for title, when I'd renamed it titlex. How can I have spent two 
weeks struggling with something so simple?

Oh well. All works now. Many thanks for your help.

I tried this and it seems to work fine - except for

I just updated to the latest CVS, and your fix has made text() work. 
Thanks.

What version are you using? Here's what I got:

#{query/music/title} => Song


Hmm. Still not working. So, I've set up a more thorough test 
environment, and let me detail again what's going on:

Sitemap:
    <map:match pattern="test">
      <map:call function="test"/>
    </map:match>
       <map:match pattern="test-pipe">
      <map:generate type="jx" src="xml/test.jx"/>
      <map:serialize type="xml"/>
    </map:match>
Flow:
function test() {
 var builder = 
Packages.javax.xml.parsers.DocumentBuilderFactory.newInstance().newDocumentBuilder(); 

 var test = builder.parse(new 
java.io.File("d:/documents/cocoon/tuneballoon/site/xml/test.xml").toURL().toExternalForm()); 

 print ("Test node:" + test.getDocumentElement().getNodeName());
 cocoon.sendPage("test-pipe", {"test": test});
}
JXTemplate (xml/test.jx):
<?xml version="1.0" encoding="UTF-8"?>
<page xmlns:jx="http://apache.org/cocoon/templates/jx/1.0";>
 <content>
     TITLE:{#{test/music/title}}
   TITLE2:(#{test/music/title/text()})
   <table>
     <jx:forEach select="#{test/music/arrangements/arrangement">
        <tr><td>TITLES:#{./title}</td></tr>
     </jx:forEach>
   </table>
 </content>
</page>
Sample XML (xml/test.xml):
<music>
 <title>Song</title>
 <arrangements>
   <arrangement>
     <title>Arr1</title>
   </arrangement>
   <arrangement>
     <title>Arr2</title>
   </arrangement>
 </arrangements>
</music>
Now, if in the within the jx:forEach I do #{.}, I get 
'TITLES:[EMAIL PROTECTED]'. 

If I do #{./title}, I get:
file:/d:/documents/cocoon/tuneballoon/site/xml/test.jx:9:35:org.apache.commons.jxpath.JXPathException: 
No pointer for xpath: ./title

If I do #{./title/text()}, I get:<tr><td>TITLES:</td></tr>, i.e. 
nothing back.

For the first two jxpaths, I get 'Song' for 
#{test/music/title/text()}, correctly, but <title>Song</title> for 
#{test/music/title}.

Perhaps you could send me the files for your working version, and I 
can see if I can get them to work here?

Thanks for your help.

<jx:forEach select="#{query/music/arrangements/arrangement}">
title: #{./title},
</jx:forEach>           => title: Arr1, title: Arr2

I've got two problems with JXTemplateGenerator. To start with, 
here's an XML:

<music>
 <title>Song</title>
 <arrangements>
   <arrangement>
     <title>Arr1</title>
   </arrangement>
   <arrangement>
     <title>Arr2</title>
   </arrangement>
 </arrangements>
</music>
1) If I call the page with this in a DOM, with the name 'query', if 
I do #{query/music/title}, it returns <title>Song</title>, not 
'Song'. #{query/music/title/text()} doesn't return anything, 
neither does string() or node().

2) If I use
<jx:forEach select="#{query/music/arrangements/arrangement">
      <tr><td>title: :#{./title}</td></tr>
</jx:forEach>
It shows one 'title:' heading, not two. But #{./title} returns 
nothing. Everything I've tried still returns nothing.

Any pointers?

Thanks, Upayavira
