XEGER or rxrdg in URL search field

What is XEGER?
Think of it as the opposite of regular expression matchers. This library allows you to generate text that is guaranteed to match a regular expression passed in.

What is rxrdg?
Regular Expression Random Data Generator


It would be nice to have that feature, for example a urlpattern for a detail-site which contains the information i want to scrape is this:

www.sampleurl.com/bacd
www.sampleurl.com/aacd
www.sampleurl.com/aadd

now you can use http://code.google.com/p/xeger/ or http://code.google.com/p/rxrdg/ and Regex code to generate the urls out of a regexpattern like:

www.sampleurl.com/(?:';|[a-d]{4})
