RE: storing the result of a transformation in a param
String-length only works if $content is a text node, on a result tree fragment, it returns false every time. I need something that evaluates to true when a result tree fragment is present in the variable. I found that I can use an extension function like so: <xsl:param name="nodeSet" select="exsl:node-set($content)"/> <xsl:value-of select="boolean($nodeSet/*)"/> This converts $content to a node set that can be navigated with XPath but it uses an extension. Is there a standard way to do it? I can't find one and I'm running out of manuals...

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
