How can I test if the variable $xsd_node was assigned a value? In some cases the node-set expression to fill this variable might copy nothing. ... <xsl:variable name="xsd_node"> <xsl:copy-of select="$xsd_doc//xs:element[@name = $name and count(child::node()) = 0]"/> </xsl:variable> <xsl:if test="???"> ... Is there something like empty($xsd_node)? Cheers, R.
