perlmonks.org has no "middle module", but you know this isn't right because the page you actually want to scrape is over at juniper.net (did you check their terms of use?). As previously discussed, please read and understand PerlMonks for the Absolute Beginner (and don't ignore the formatting advice displayed when posting How do I post a question effectively?).
You were given lots of links previously for tools to make this job easy for you, the exampe above isn't based on this advice, rather old content from Perl & LWP.
