The function position() will give you the position of the node you are currently processing in the list, and last() will give you the position of node that's last in the list. So, you only want to output a comma if the position of the node you are processing is not the last one: <xsl:if test="position() != last()">, </xsl:if> cheers andrew XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
