PlistParser does not rely on any external libraries like jQuery or JSON. It was written for use within the Appcelerator Titanium environment, but also works with modern browsers. Tested in Titanium, Firefox, IE, Safari, Chrome, and Opera.
Include 'plist_parser.js' via an HTML script tag or Titanium.include().
var jsonString = PlistParser.parse(xmlString);
