RegexPal
RegexPal is a simple web-based regular expression tester written entirely in JavaScript.
To test a regular expression using RegexPal, open regexpal.com in your browser and type a pattern in the box at the top. In the bottom box, enter the target text you want to match.
You will see that RegexPal automatically highlights the portion of the text that matches your regex. The program also indicates any syntax errors in your pattern. A nice feature of RegexPal is the ability to provide information as you type without the need to click on a button to see the result, making it very convenient to use.
