Re: keyed lookup table
Kevin,
Are you using the key() function in its New Improved XSLT 2.0 version?
In XSLT 1.0, it won't take the third argument, and you have to change
context to the stylesheet explicitly (probably by using a for-each) to get
it to work the way you want.
But I'd expect, if that's the problem, you should be getting an error. If
you're using XSLT 2.0 ... I'll let someone else address that, as the tools
are new. (You should tell us which processor you're using, however.)
Cheers,
Wendell

I've got a working lookup table implemented like this:
<xsl:variable name="language-table">
<!-- See ISO 639 -->
<name code="ar">ARABIC</name>
<name code="de">GERMAN</name>
<name code="en">ENGLISH</name>
...
<name code="zh">CHINESE</name>
</xsl:variable>
that I can access in my templates with an expression like:
$language-table/name[@code='de']
I was hoping I could access that table via a key:
<xsl:key name="language-code" match="name" use="@code"/>
that I would access with this expression:
key('language-code', 'de', $stylesheet)"/>
given:
<xsl:variable name="stylesheet" select="document('')"/>
But the key function always returns an empty sequence. Why? Can I use
a key on these $language-table/name nodes, which are internal to the
stylesheet? (I'm sure it will work if I move the lookup table from the
stylesheet to its own external XML document, which is more maintainable
anyway, but I want to udnerstand what is wrong with the idea of a keyed
lookup table within the stylesheet.)
