RE: building a nodeset from selected nodes

Hi Wendell,

Using key() is sooooo much easier than recursive templates.

I originally thought of doing this (assuming I understand you) but
then I got back to the problem where I have multiple node-sets with
no obvious (to me?) way to combine them into a single node-set, though
I was eventually able to combine them using recursive template calls.

<xsl:for-each select="column">
  <xsl:apply-templates select="key('columns-by-name', .)"/>
</xsl:for-each>

Is there a simpler approach to combine a variable number of node-sets
into a single node-set (without using extensions)?

<xsl:template match="query">
  <xsl:variable name="matching-columns"
       select="//table/column[name=current()/column]"/>
  <xsl:for-each select="$matching-columns">
     ...
  </xsl:for-each>
</xsl:template>

Cheers,
Wendell
