Subject: RE: [xsl] xsl:perform-sort sequence problem From: "Michael Kay" <mike@xxxxxxxxxxxx> Date: Mon, 22 Oct 2007 13:01:25 +0100 |
xsl:perform-sort is delivering a sequence of strings, and your xsl:variable is then concatenating these into a single text node. Use <xsl:variable as="xs:string*"/> if you want a sequence of strings, or as="attribute(date)*" if you want a sequence of attribute nodes.
