keyed lookup table
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.) Thanks, -- Kevin
