Others have pointed out Learning Perl and The Perl Cookbook as good sources. You ought to be able to cobble something together in a few hours if you know how to skim effectively. You might want to look at Picking Up Perl, as it's online and free.

Some people have suggested CPAN, and generally I agree that CPAN is the way to go when you need to do something. However, for a complete newb and for this task, I'd suggest sticking with straight forward DIY parsing code. The CPAN options will all require understanding data structures and references and such--not to mention module installation. Skip that crap, it's more work than it's worth at this point. At first you take baby steps. Learning to use CPAN will allow you to run, but you are definitely not ready yet.

Post your code when you get stuck.
