Tackle this as a two phase transformation, phase one to do the summation and phase two to do the sorting. Put the intermediate results in a result tree fragment, and process it for phase two using the xx:node-set() extension function that comes with your chosen processor. <xsl:variable name="phase1out"> <xsl:apply-templates select="/" mode="phase1"/> </xsl:variable> <xsl:template match="/"> <xsl:apply-templates select="xx:node-set($phase1out)" mode="phase2"/> </xsl:template> Mike Kay XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
