It is working... This seems unlikely. I'm still a little confused on the parm(s) but no worries!

In this case however it prduces nothing as there are no row element children of the current node (the only child of / is a in_proc element (I guess, you have not shown your input format) <xsl:if test="$current_id = $activity_id"> this test is always true (given the default value of $xm) as $current_id is an attribute node from the set $activity_id Even if you supply an xm parameter so that the tests may be false, <xsl:apply-templates select="$xm/row" mode="append"/> <xsl:template match="row" mode="append"> <xsl:variable name="current_id" select="@id"/> <xsl:if test="$current_id = $activity_id"> <xsl:copy-of select="."/> </xsl:if> </xsl:template> is equivalent to <xsl:copy-of select="$xm/row[@id = $activity_id]"/> David ________________________________________________________________________ This e-mail has been scanned for all viruses by Star.
