sum and substring xpath needed
Hi all, Please can someone give me the xpath that will sum() the following values into the select attribute of a variable (ie not a rtf). <colspec colwidth="38mm"/> <colspec colwidth="22mm"/> <colspec colwidth="26mm"/> <colspec colwidth="43mm"/> so something like: <xsl:variable name="total" select="sum(substring-before(//tgroup/colspec/@colwidth,'mm'))"/> ..this obviously fails because sum() requires a node-set and the substring functions return strings, but you get the idea. I dont think its possible to do in a single select but you never know, hopefully there's some trick available. cheers andrew --- Outgoing mail is certified Virus Free.
