RE: multiple sorting

[Joshua Allen <joshuaa at microsoft dot com>]

Sorting dynamically client-side really implies that
your browser supports XML (which means IE today) and
if you are using <xsl:sort..> means that they have
a current version of the XSLT processor installed
on the client.  Given these conditions, you can
use something similar to the sample at
http://msdn.microsoft.com/xml/samples/portfolio/sort.htm
the basic idea is the you use javascript to create
the filtered/sorted output and use DHTM .innerHTML to
place this in an element somewhere.  The example above
does not do any pretty formatting, but I pointed to it
because it should be easy to understand, and you should
be able to see from there if you will need to change the way
the DOM is accessed or something to make it compatible with
Netscape 6 when it releases.  Also you may want to
experiement with that version calling XSLT transform. 
The basic idea is to use DHTML DOM, which is illustrated 
there though.  For a dynamic client sort sample with prettier 
formatting, see
http://msdn.microsoft.com/xml/samples/stock-sorter/stock-sorter.xml.
