RE: [xsl] sort and order xml data according to what user selects from a form

Subject: RE: [xsl] sort and order xml data according to what user selects from a form From: "Lars Huttar" <lars_huttar@xxxxxxx> Date: Fri, 18 Jul 2003 23:51:01 -0500 |
This FAQ item
http://www.dpawson.co.uk/xsl/sect2/N6461.html#d6859e950
tells how to set the sort order dynamically.
In brief, something like
<xsl:sort order="{$order}" select="*[name()=$sortByField]"/>
This says "sort elements by their child element whose name
is the value of $sortByField".
So if $sortByField = 'size', you will be sorting publication elements
by the value of their size element child.
Let us know if you try this and are still stuck...
