JX node not showing
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

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.

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

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

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:org.apache.cocoon.generation.JXTemplateGenerator$Expression@177ff35'.
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.

Re: JX node not showing

I tried this and it seems to work fine - except for
#{query/music/title/text()} which caused a NullPointerException. I just
checked in a fix for that. What version are you using? Here's what I got:
#{query/music/title} => Song
<jx:forEach select="#{query/music/arrangements/arrangement}">
title: #{./title},
</jx:forEach> => title: Arr1, title: Arr2
