Subject: [xsl] storing the result of a transformation in a param and evaluating the content From: Jean-François Lavigne <jf_lavigne@xxxxxxxxxxxx> Date: Mon, 22 Nov 2004 21:51:34 -0500 |
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
