try <xsl:if test="string-length(content)>0"> best, Tiffany_Blake@xxxxxxx -----Original Message----- From: Jean-Frangois Lavigne [mailto:jf_lavigne@xxxxxxxxxxxx] Sent: Monday, November 22, 2004 6:52 PM To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: [xsl] storing the result of a transformation in a param and evaluating the content Hello all, If I store the result of a transformation into a variable, is there a way to check this variable to see if it contains an element or nothing? For example: <xsl:template name="item"> <xsl:param name="content"> <xsl:apply-templates/> </xsl:param> <xsl:copy-of select="$content"/> </xsl:template> The copy-of element returns $content which is: <world>hello</world> What if the apply-templates element returned nothing and $content is empty. Is there a way to check for this situation? Thanks a lot. J-F
