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[(_at_)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.)
Thanks,
