On CatsWhoCode.com today there's a new article listing fifteen handy regular expressions you might find useful in your day-to-day development (as well as a brief introduction to what regular expressions are).

Regular expressions are a very useful tool for developers. They allow to find, identify or replace text, words or any kind of characters. In this article, I have compiled 15+ extremely useful regular expressions that any web developer should have in his toolkit.

Here's just some of the expressions on the list:

• Enlight a word from a text
• Remove repeated words (case insensitive)
• Matching a XML/HTML tag
• Matching hexadecimal color values
• Parsing Apache logs
