XML::Parser is the granddaddy of them all.  If all you need is simple parsing try 
XML::Simple which sits on top of it, for basic parsing.  AxKit was also mentiond 
(but needs mod_perl).  XML::Parser uses a native C library under the covers.  
There are versions of SAX and XML::Simple that are pure perl based, but of 
course this means you will take an even bigger performance hit.

Go to CPAN and search on XML and XSLT....you'll find a heap of pre-written 
packages there.

I just recently did this exact same thing.  Easily done...but there are some big 
caveats you need to be aware of:

1) If you are not hosting your own server (ie. using an ISP) then you may need 
to get them to install whatever you select.  Or pick a solution that is pure Perl 
(eg. no C routines) which you can install yourself (and prepare for the 
performance hit).

2) Performance will [expletive deleted] big time....unless you implement under mod_perl. For 
example...I was going to use XML for config files for my CGI scripts....but it 
added a huge overhead to the CGI script startup that was not worth it.  (As an 
aside, what I did was still put the configs in XML format...but then ran a 
transform that converted the XML config into a native Perl executable script, 
which is then used at runtime....way lower overhead). If this will be a heavily 
used app, every time your CGI gets hit, the web server/perl combo will have to 
load all the XML stuff...which takes a long time.  mod_perl fixes this by 
loading/compiling this stuff only once....but can be tricky to implement and 
virtually impossible if you are using an external ISP (hardly any suppport 
mod_perl).

Hope this helps....
