> How do you write the xpath to calculate the sum or a*b for the this is a faq. You can not do it in a single xpath. easiest is to generate a result tree fragment with the list of products <xsl:variable name="x"> <xsl:for-each select="item/data[@id=2]"> <x><xsl:value-of select="a * b"/></x> </xsl:for-each> </xsl:variable> then use your processors node-set() extension to sum <xsl:value-of select="sum(xx:node-set($x)/x"/> David _____________________________________________________________________ This message has been checked for all known viruses by Star Internet delivered through the MessageLabs Virus Scanning Service.
