xml-dev - Implementing user input in XSL

[EWDProductions@aol.com]

For starters, hello.  This is my first post to the forum and I look forward 
to getting to know alot of you well in my endeavor to learn this language.

I've already read through a multitude of sites on XML and its supporting 
languages and even purchased a book.  What I'm curious about is if it would 
be possible for a visitor of my site pull up a "Table" of data. 

For example, I have a list of products, prices, reviews, and shipping prices. 
 I want to be able to make a drop downlist that has each of the 4 options and 
when one is selected, the list is reordered based on that value.  For 
example, if they chose reviews, it resorts the list based on the best reviews 
to worse.  

What I've been able to come up with is a script that will load a different 
xsl file to format the xml.  1 file for each option.  Now that's not 
including reverse odering.  I'm on 6 files for one page and if I were to 
implement searches and reverse orders, I'd be well over twenty.  

Is there a way for <.xsl:sort> to process a variable instead of a text or 
prescribed element?
