RE: [xsl] Sorting with Javascript.

["Michael Kay" <mhk@xxxxxxxxx>]

Your problem is an HTML/Javascript problem and not an XSLT problem, so
you may be disappointed.

I'm amazed by the idea of writing your own sort routine to tackle this
problem. I don't know enough Javascript to suggest a better way,
however. Many people achieve this effect by using client-side
stylesheets.
