Should I use a Key to index > all the indexterms from all the XML files? xsl:key always works within a single document, but xsl:for-each-group works on any sequence, including a sequence containing nodes from multiple documents. So stick with for-each-group. > > Here is my XSLT so far with the added Document function.

Something like for-each-group select="$XML1/manual/title/document(.)//indexterm" Michael Kay http://www.saxonica.com/
