RE: AW: recursion with xsl:apply-templates

><xsl:copy-of select="xalan:nodeset($indexToIDs)/entry[@genid =

Just one further thing...  I would suggest converting to a nodeset
outside of the iteration, so that it only gets performed once rather
than once per interation.

So if you have a global variable holding information that you will
query, add another variable beneath it that holds it as a nodeset, just
like:

<xsl:variable name="indexToIDs-rtf">
   <xsl:for-each select="/transformation/IRF//*[@index]">
     <xsl:variable name="pos" select="position()"/>
     <entry genid="{generate-id()}">
       <xsl:copy-of select="/transformation/id_list/id[$pos]"/>
     </entry>
   </xsl:for-each>
</xsl:variable>
<xsl:variable name="indexToIDs" select="exsl:node-set($indexToIDs)"/>

..and then reference the nodeset each time (notice the name changes).  I
don't know the figures but I would guess converting to a node-set is
more than just setting a boolean in the processor, so it's best done
once only (maybe someone knows).
