Hi Sudhir, > I would like to call error-template in case > > A. I don't find the node "format/tr[2]/td[position()>1]", or The test here is just: not(format/tr[2]/td[position() > 1]) > B. The value of format/tr[2]/td[position()>1] is "NA" >From your code, I think you want to know if *all* the tds following the first are equal to 'NA'. You have to turn the XPath around to make that test - you want to know if it's *not* the case that *at least one* of the tds is *not equal to* 'NA': not(format/tr[2]/td[position() > 1] != 'NA') So the XSLT should be: <xsl:variable name="cells" select="format/tr[2]/td[position() > 1]" /> <xsl:choose> <xsl:when test="not($cells) or not($cells != 'NA')"> <xsl:call-template name="error-template" /> </xsl:when> <xsl:otherwise> <xsl:apply-templates select="format" /> </xsl:otherwise> </xsl:choose> I hope that helps, Jeni --- Jeni Tennison http://www.jenitennison.com/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
