Re: NodeTest expected here - problem with creating xs

Hi Malcom,

The only functions allowed in a pattern are id() and key(). So you just need
to get around that.

Something like this, but you can probably do better:

<xsl:variable name="lookup" select="document('LookupTable.xml')" />
<xsl:key name="keyedLookupTable" match="LookupTable/Value" use="@key"/>

<xsl:template match="/">
<Output>
<xsl:for-each select="/Data/key">
<xsl:variable name="currentKey" select="."/>
<data>
<xsl:value-of select="$lookup[key('keyedLookupTable' , $currentKey)]"/>
</data>
</xsl:for-each>
</Output>
</xsl:template>

Subject:  NodeTest expected here - problem with creating xsl:key from

application has a large lookupTable and data file so I need the speed
available from a key.
