parsing form with a website question...

Hi guys... Got a question that I figured I'd ask before I reinvent the wheel. A basic website has a form, or multiple forms. within the form, there might be multiple elements (lists/select statements, etc...). each item would have a varname, which would in turn be used as part of the form action, to create the entire query... sort of like: form action=test.php? option name=foo foo=1 foo=2 foo=3 foo=4 /option option name=cat cat=1 cat=2 cat=3 /option /form so you'd get the following urls in this psuedo example: test.php?foo=1&cat=1 test.php?foo=1&cat=2 test.php?foo=1&cat=3 test.php?foo=2&cat=1 test.php?foo=2&cat=2 test.php?foo=2&cat=3 test.php?foo=3&cat=1 test.php?foo=3&cat=2 test.php?foo=3&cat=3 test.php?foo=4&cat=1 test.php?foo=4&cat=2 test.php?foo=4&cat=3 i'm looking for an app that has the ability to parse any given "form" on a web page, returning the complete list of possible url combinations based on the underlying elements that make up/define the form... anybody ever seen anything remotely close to this...??? i've been research crawlers, thinking that this kind of functionality would already exist, but so far, no luck! thanks
