Introduction To Regular Expressions In PHP
In Linux and Unix, the syntax that is commonly used by many applications for specifying text patterns is known as regular expressions or in short form – regex.
Useful Perl Scripts With Regular Expressions
Most computer users, especially software engineers, have had a need to modify multiple files to either add a line of text, modify a line of text, or completely remove a line of text. The problem is that there never seems to be a piece of software out there that can help you with this problem.

There is no version of SQL Server that supports regular expressions natively, but I discovered a way to add all sorts of regular expression goodness to your T-SQL applications. In order to use regular expressions easily, we can use a User Defined Function to help us out and abstract the work for us.
