<xsl:variable name="reg"> <xsl:for-each select="//reg"> <xsl:copy-of select="."/> </xsl:for-each> </xsl:variable> .. <xsl:when test="$reg/ Note that's not legal in XSLT1 (as $reg is a result tree fragment) it's legal but expensive in xslt2 (as you have to copy all the nodes) better to do <xsl:variable name="reg" select="//reg"/> An alternative strategy would be <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="top"> <xsl:for-each select="a/reg"> :<xsl:variable name="x" select="(.|preceding-sibling::reg)[@offset][last()]"/> <xsl:value-of select="."/>: <xsl:value-of select="sum($x/@offset) + count(preceding-sibling::reg) - count($x/preceding-sibling::reg)"/> </xsl:for-each> </xsl:template> </xsl:stylesheet> David ________________________________________________________________________ This e-mail has been scanned for all viruses by Star.
