Subject: [xsl] Putting a nodeset in a variable From: Cams Ismael <Ismael.Cams@xxxxxxxxxxxxxxx> Date: Fri, 22 Nov 2002 14:10:21 +0100 |
Hello, is it possible to put a nodeset in a variable. What I try to do is the following. I have an xml file which I want to group. This resulting tree I want to put in a variable so I can use it later on. E.g. <traps> <trap id="5"/> <trap id="6"/> <trap id="2"/> <trap id="5"/> </traps> <xsl:variable name="distinctValues"> <traps> <xsl:for-each select="traps/trap"> <xsl:sort select="./@id"/> <xsl:copy-of select="."/> </xsl:for-each> </traps> </xsl:variable> <xsl:template match="/"> <xsl:for-each select="$distinctValues/trap"> <xsl:value-of select="@id"/> </xsl:for-each> </xsl:template> When I try to do this I get following error: Expression must evaluate to a node-set. Can somebody give me a hint if this is possible ? Kind regards, Ismaël XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
