in reply to Easiest Way To Cut Info from Webpages

Have a look at HTML::Parser or HTML::TokeParser. If you just want to get the job done, chances are good that what you want is unique enough to pull out with a regular expression. I don't normally recommend regexes for this kind of job, but they do get the job done. At any rate, you will want to fetch the web page so you can parse it, and for that i recommend WWW::Mechanize. In conclusion, parsing web pages is generic, but parsing a specific web page is not, so you probably will not find an existing script for the website you are trying to parse, and if you do, the chances are good that it won't work for you. This is why you generally have to start from scratch, and inspect the HTML you are trying to parse with your own two eyes. And yes, as soon as the WebMaster changes the HTML, your script will probably break. :)
