Title Test Details Pattern Title
Expression
(?!^[0-9]*$)(?!^[a-zA-Z]*$)^([a-zA-Z0-9]{6,15})$
Description
I built this expression to test a string in ASP for valid username and password constraints. It can be adapted for any number of scenerios. For instance in this case, we needed to ensure the username someone wanted was not all numbers or all letters and was 6-15 characters in length with no special characters. This expression tests negatively for all number cases, then all letter cases, and lastly tests for only alphanumeric characters in the required range. In other words: the match must be alphanumeric with at least one number, one letter, and be between 6-15 character in length.

^([0-9a-zA-Z]+[-._+&])*[0-9a-zA-Z]+@([-0-9a-zA-Z]+[.])+[a-zA-Z]{2,6}$
Description
A short and sweet email address validator. Checks that the username starts and ends with an alphanumeric character, allows a few non-repeating 'special characters' (namely -, ., _, +, &) and checks for a sensible domain name (2-6 character TLD required). Some unconventional, yet technically valid, addresses will not be matched, but this is only a simple expression ;-)

Title Test Details Matching urls in free text

Description
A regular expression which allows me to find strings of text floating around in free text that are in fact URLs. I need to tag these as <url>www.bmj.com/advice</url>.

Each domain label must be between 1 and 63 characters long, while the total length of the domain name may not exceed 255 characters.
