My first guess would be to use copy-of instead of value-of in your nodeset-generating templates..
What does <xsl:copy-of select="$aux" /> yield?

I guess it shoud work with <xsl:value-of select="$aux/*/item[ @handle='a1' ]" /> or <xsl:value-of select="$aux/some-doc/item[ @handle='a1' ]" />.

What does
<xsl:copy-of select="$aux" />yield?
<a>
<data>
<item handle="a1">a1</item>
<item handle="a2">a2</item>
<item handle="a3">a3</item>
<item handle="a4">a4</item>
</data>
</a>
<b>
<data>
<item handle="b1">b1</item>
<item handle="b2">b2</item>
<item handle="b3">b3</item>
<item handle="b4">b4</item>
</data>
</b>
<xyz xmlns:exsl="http://exslt.org/common">
<data>
<item handle="handle-of-bla">bla</item>
<item handle="handle-of-xyz">xyz</item>
<item handle="cute-handle">foo</item>
<item handle="bar*2">bar</item>
</data>
</xyz>
Solved. Wasn't looking at the markup of the result, but only to what browser outputs.
<xsl:value-of select="$aux/a/data/item[1]" />
Triggers an error
XSLTProcessor::transformToXml(): Invalid type
XSLTProcessor::transformToXml(): XPath evaluation returned no result.XSLTProcessor::transformToXml(): runtime error: file file:[...]/pages/doc.xsl line 53 element value-of
But this works:
<xsl:value-of select="$ns_var/a/data/item[1]" />
outputs a1.
Thanks both for advices :)

Using <xsl:copy-of select="document('xyz.xml')/data" /> doesn't help?

Oh and I think
<xsl:variable name="ns_var" select="exsl:node-set($aux)" />
doesn't make much sense. $aux already is some XML. You make it accessible to xpath etc by using exsl:node-set(). But putting the result in another variable... You'd have to use exsl:node-set($ns_var) again to make that variable accessible to xpath.

I edited the comment above. Solved it. It is interesting tough that I have to wrap $aux in exsl:node-set() to another variable.

In reply to your comment no.6, look at my comment (no.5), last part. It seems that I had to wrap it in exsl:node-set() to work ...

I have a situation where I need to load an unknown number of external
.xmldocuments and access data from them.a.xml <data> <item handle="a1">a1</item> <item handle="a2">a2</item> <item handle="a3">a3</item> <item handle="a4">a4</item> </data> b.xml <data> <item handle="b1">b1</item> <item handle="b2">b2</item> <item handle="b3">b3</item> <item handle="b4">b4</item> </data> xyz.xml <data> <item handle="handle-of-bla">bla</item> <item handle="handle-of-xyz">xyz</item> <item handle="cute-handle">foo</item> <item handle="bar*2">bar</item> </data>My idea is to load these documents in a variable and access them from there:
<xsl:variable name="aux"> <doc-a> <xsl:value-of select="document('a.xml')/data" /> </doc-a> <doc-b> <xsl:value-of select="document('b.xml')/data" /> </doc-b> <xsl:call-template name="add_more_docs" /> </xsl:variable> <xsl:template name="add_more_docs"> <doc-xyz> <xsl:value-of select="document('xyz.xml')/data" /> </doc-xyz> </xsl:template>Usage would be like this:
The problem is that I cannot access them like a node-set ... I tried to:
but without success.
Any ideas how can I add multiple node-sets to the same variable? Thanks.
