Regular Expressions Resources
Lately, I have been working a lot with regular expressions and today I want to expand on my Best Programming Cheat Sheets post and Grep, Awk, and Sed post and list some great resources on finding useful Regex patterns and examples. If you are just starting out in Regex land, I would highly recommend reading through Smashing Magazine’s Guide to Regular Expressions and practice some patters with RegexPal or JS Regex Tester. These tools are really useful in testing and validating different patterns so keep them in mind as you browse through the Regex resources below:
