Oddly enough, IO::All may provide the server side relatively painlessly, as well. Its docs seem to talk about a one-line web server that does CGI, which I thought was an oddity, and here you may find it quite useful (I'd suggest some more whitespace, and, perhaps, a slightly more advanced usage, but the one-liner may get you started). Then use one of the myriad of XML modules to parse the XML - depending on what you're dealing with, XML::Simple may suffice, although XML::Twig has always been my favourite.
