XRegExp 1.1.0

XRegExp 1.1.0 is known as a useful and convenient product which provides an augmented, extensible, cross-browser implementation of regular expressions, including support for additional syntax, flags, and methods.

XRegExp is fully compliant with the regular expression flavor specified in ECMA-262 Edition 3 (ES3), and has been tested with Internet Explorer 5.5–8, Firefox 2–3.5, Safari 3–4, Chrome 1–2, and Opera 9. XRegExp uses feature detection—no browser sniffing.

Major Features:

1. Adds new regex and replacement text syntax, including comprehensive support for named capture.
2. Adds two new regex flags: s, to make dot match all characters (aka singleline mode), and x, for free-spacing and comments (aka extended mode).
3. Provides a suite of 12 functions and methods that make complex regex processing a breeze.
4. Automagically fixes the most commonly encountered cross-browser inconsistencies in regex behavior and syntax.
5. Lets you easily create and use plugins that add new syntax and flags to XRegExp's regular expression language.

• New feature: A bug in IE where the lastIndex property of regexes created with the /g flag is not always reset to zero after running String.prototype.replace or String.prototype.match is now fixed automatically.
• New feature: A bug in Firefox, IE, Safari, and Chrome where the lastIndex property of a regex is not updated during String.prototype.replace iterations (visible within replacement functions) is now fixed automatically.
• Fix: String.prototype.split and String.prototype.replace now consistently work with non-string context (this).
• Fix: The empty character class [] caused incorrect results in some edge cases in Firefox only, due to a Firefox bug in handling empty negative lookahead.
