I guess this must be in the xsl-FAQ -- search for lookup.

You have to be sure that the current document is the one you want to search.
This can be done using the following code:

  <xsl:for-each select="document('whateverURI')">

   <!-- Use the key() function, e.g.: -->
   <xsl:copy-of select="key('CurrentGroupByIdentifier', 'xxx')"/>

  </xsl:for-each>

The purpose of the xsl:for-each above is only to make the necessary document
the current document. As it specifies a node-list of only one node (the root
node of the document), the body of this xsl:for-each instruction will be
applied only once, which is exactly what we want.
