XRegExp is an open source (MIT License) JavaScript library that provides augmented, extensible regular expressions. You get new syntax, flags, and methods beyond what browsers support natively. XRegExp is also a regex utility belt with tools to make your client-side grepping simpler and more powerful, while freeing you from worrying about pesky cross-browser inconsistencies and the dubious lastIndex property.
XRegExp is fully compliant with the regular expression flavor specified in ES3 and ES5. It works with Internet Explorer 5.5+, Firefox 1.5+, Safari 3+, Chrome, and Opera 9.5+. You can also use it on the server with Node.js.
