Subject: [xsl] unique attribute values in XSLT2 - storing them in a variable From: <jozef.aerts@xxxxxxxxxxxxxx> Date: Tue, 22 Feb 2005 11:52:04 +0100 |
Dear all, I am making the transition now from XSLT1 to XSLT2 I have the following XML: <?xml version="1.0" encoding="UTF-8"?> <A at1="1" at2="2"> <B atb="3"> <C atc="a"/> <C atc="b"/> </B> <B atb="3"> <C atc="a"/> <C atc="c"/> </B> </A> I need to find all unique values of the @atc attribute, and store them in a variable for later use. That was no problem in XSLT1, but I still have some problems in XSLT2. This is what I have: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0"> <xsl:template match="/"> <xsl:apply-templates select="A"/> </xsl:template> <xsl:template match="A"> <xsl:for-each-group select="B/C" group-by="."> <xsl:sort select="." /> <xsl:value-of select="." /> <xsl:for-each select="distinct-values(current-group()/@atc)"> distinct @atc = <xsl:value-of select="." /> </xsl:for-each> </xsl:for-each-group> </xsl:template> </xsl:stylesheet> This indeed gives: distinct @atc = a distinct @atc = b distinct @atc = c But how do I store these values in a variable for later use ? Many thanks in advance Jozef
