I just looked at the source of the page you provided. You're quite lucky in this case, the webmaster seems to have dumped all relevant information into the body as well as into the meta tags.

If i where you, i'd look into something like

• WWW::Mechanize::GZip to fetch the files, "click" links and fill out forms.
• Regular expressions to get the information line-by-line from the META tags into a hash.
• think about perl functions like open, print, close to write a CSV file. You know,
• foreach field of the required fields write the properly quoted content and add a semicolon and don't forget the newline at the end.

I'm specifically vague, but following the list should give you a (simple, ugly) quickhack solution for your problem. It will break if the webmaster removes or changes the meta lines. But if this is a onetime job, it should work.

Of course, if you need something flexible, reliable that will work for some years, you should really take a look into real HTML parsers.
