You'll need LWP::Useragent, or for a minimal approach LWP::Simple (which
comes with the same packate) for requesting your page from the server.
Then you'll need HTML::Parser for reading and parsing your webpage.
Both modules and their dependencies are available from the CPAN and come
with a lot of documentation and sample code.
Once you've installed them, I suggest starting with
perldoc lwpcook
which is the libwww-perl cookbook. From there on, you can decide if
it's sufficient to use LWP::Simple or if you need the full fledged
LWP::UserAgent.
Once you have your page, depending on what you need to do with it, You
can either use HTML::Parser to do everything on your own, or use one of
the available sub modules like HTML::LinkExtor or HTML::TreeBuilder.
perldoc HTML::Parser
perldoc HTML::LinkExtor
perldoc HTML::TreeBuilder
There are more modules for this kind of stuff. Click yourself through
the module hierarchy at http://search.cpan.org, perhaps you'll find
something that exactly fits your needs befor rolling your own...
Ask if you run into trouble...
