Yep. Look through WWW::Mechanize's documentation as it's a high-level module that automates web scripting. Also look at learning an HTML parser (like HTML::TreeBuilder, which uses HTML::Parser to build a tree structure out of the HTML from which you can traverse) if you need something more than a simple snippet you can get with regular expressions.
Finally, if you need more assistance ask a specific question here (although make sure you try whatever you're asking for help on doing first!) and pick up a book - Perl Cookbook is pretty popular and has an entire chapter on web automation.
