There are tons of uses for XSLT.  The simplest and most known is 
transforming XML into HTML.  XSLT  can seperate content and presentation 
simlar to HTML::Template or TT2.  But unlike these template options,  
XSLT is standard compliant and works beyond the world of Perl.  Of 
course, there are many other less known uses for XSLT.  XML 
transformation into PDF, JPEG, SQL, etc.

The Perl interface is fairly simple.  I'm guessing you're having 
problems with XSLT itself.  The documentation on XSLT for the most part 
is cut and paste from the W3C standard.  Which usually aren't the easiet 
reads.

Here are some good articles on XSLT.

If your still having problems.  I'd be happy to help of list.

XML::XPath really isn't used to manipulate XML.  Rather its used to 
extract XML data.
