Thanks Andrew but that doesn't help me. I'm using 2.0.
Here is my test/use case, I have three files test.xml is the
transformed document, include.xml is the included document and
text.xsl is the XSL.
test.xml:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="test.xsl"?>
<document
file="include.xml">
<extra type="introduction"><p>barfoo</p></extra>
</document>
include.xml:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="test.xsl"?>
<document>
<p> foobar </p>
</document>
test.xsl:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="2.0">
<xsl:key
match="extra"
name="extra"
use="@type"/>
<xsl:template
match="extra"/>
<xsl:template
match="p">
<p>
<xsl:apply-templates/>
</p>
</xsl:template>
<xsl:template
match="/document">
<xsl:choose>
<xsl:when
test="@file">
<!-- This works because the extra is in scope -->
<xsl:for-each
select="key('extra','introduction')">
<xsl:apply-templates
select="child::node()"/>
</xsl:for-each>
<xsl:apply-templates
select="doc(@file)"/>
</xsl:when>
<xsl:otherwise>
<!-- But actually we wanted to pass the extra for use
here in the second instance of "document" -->
<xsl:for-each
select="key('extra','introduction')">
<xsl:apply-templates
select="child::node()"/>
</xsl:for-each>
<xsl:apply-templates/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
Your help appreciated.
Sincerely,
Steven

For the second call to use the key on the first document you need to
do a bit of extra work in XSLT 1.0 eg
<xsl:variable name="val" select="val to use in key look up"/>
<xsl:for-each select="$first-doc">
<xsl:apply-templates select="key('keyname', $val)"/>
</
...because the key will only ever be applied to the current document,
so you have to switch back to the first document before making the
call.
XSLT 2.0 remedies this by providing a third argument to key to tell it
which document should be used:
key('keyname', value, $first-doc)
If that's a bit hard to follow, produce the test case and it will be
easier to show you with that.
cheers
