in reply to Using RSS
To get files off a remote server, you will need to use one of a selection of fine tools. If you want to pulls the files off periodically, then you can use a scheduler such as cron or at, and a standalone executable such as wGet. If you want to get the files and work on them at the same time, then Perl has some excellent tools for this: LWP::UserAgent; LWP::Simple and HTTP::GHTTP.
Once you have your XML file, you'll want to do something with it. Perl has some excellent tools for this too, including the just updated XML::RSS and my very own XML::RSS::Tools. Either way there are some nice examples and useful links in the documentation of both modules, and there is also useful stuff on XML.com
As it happens I know that the perl-rss crew are planning to update the documents of XML::RSS with some nice links to example articles soon, so you won't have to dig around too much on your own.
