While I can't address the function and button part of it, you could do the XSLT part of it with a stylesheet parameter, thus: <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:param name="order" select="descending"/> <xsl:template match="/"> <xsl:apply-templates select="//Item"> <xsl:sort select="name" order="{$order}"/> </xsl:apply-templates> </xsl:template> <xsl:template match="Item"> <xsl:value-of select="name"/> </xsl:template> </xsl:stylesheet> The select="descending" attribute on the param instruction gives you a default value in case no parameter is passed. Otherwise, whatever is passed to the stylesheet ends up in the order attribute of the sort instruction. So, you'd best be sure that it's always either "ascending" or "descending". Here's a bit safer way to do it: <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:param name="order"/> <xsl:template match="/"> <xsl:choose> <xsl:when test="$order='ascending'"> <xsl:apply-templates select="//Item"> <xsl:sort select="name" order="ascending"/> </xsl:apply-templates> </xsl:when> <xsl:otherwise> <xsl:apply-templates select="//Item"> <xsl:sort select="name" order="descending"/> </xsl:apply-templates> </xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template match="Item"> <xsl:value-of select="name"/> </xsl:template> </xsl:stylesheet> The choose instruction protects you from people passing in garbage for the parameter and still gives you a default behavior. However, it makes the stylesheet much more verbose (which some folks seem to hate).

Does anybody have any ideas? Thanks, Craig. <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:template match="/"> <xsl:apply-templates select="//Item"> <xsl:sort select="name" order="descending"/> </xsl:apply-templates> </xsl:template> <xsl:template match="Item"> <xsl:value-of select="name"/> </xsl:template> </xsl:stylesheet> _________________________________________________________________ Find a job, book a flight, search for a car - visit MSN South Africa! http://www.msn.co.za/
