Regular Expressions are originally from Perl. They are a very powerful syntax method for text parsing and processing. With a well formed regular expression you can reduce 5 or 10 lines of programming code.

Here is a link about them:

I really recommend anyone who is doing a lot of text processing, to learn, use and know regular expressions. I was already fluent w/ them because of my Perl experience, but a lot of .NET developers haven't really looked into their power yet.
