Subject: sorting and parameters From: Perry Roland <pdr4h@xxxxxxxxxxxxxxxxxxxxxx> Date: Mon, 17 Jan 2000 09:04:25 -0500 |
I'm greatly appreciative of the help I've received from the list. I think I'm learning a lot, but I've run up against another stumbling block: How do I pass a sort key to a stylesheet? Here's my XML -- <list> <item> <title>Blurf</title> <num>1</num> </item> <item> <title>Barf</title> <num>2</num> </item> </list> I want to be able to sort by title or by num using the same stylesheet. Here's my stylesheet -- <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:param name="key">title</xsl:param> <xsl:param name="sortorder">ascending</xsl:param> <xsl:template match="/"> <HTML> <HEAD><TITLE></TITLE></HEAD> <BODY BGCOLOR="#ffffff"> <xsl:apply-templates select="hitlist"/> </BODY> </HTML> </xsl:template> <xsl:template match="list"> <UL> <xsl:apply-templates select="item"> <xsl:sort select="{$key}" order="{$sortorder}"/> </xsl:apply-templates> </UL> </xsl:template> <xsl:template match="item"> <LI> <xsl:value-of select="title"/><BR/> <xsl:value-of select="num"/> </LI> </xsl:template> </xsl:stylesheet> Using Saxon, I get the error "Invalid character ({) in expression {$key}". I think the syntax is right because I have no problem with the sortorder parameter. I suspect the difference may be because the sortorder parameter is a string while the key parameter is a collection of nodes, but I don't know how to proceed from there. Any help would be greatly appreciated. -- perry XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
