rephrase § E4X
http://rephrase.net/days/07/06/e4x
"E4X, short for “ECMASCript for XML”, is an extension to ECMAScript (i.e. JavaScript, JScript, ActionScript…) with new syntax and built-in objects for more convenient handling of XML fragments. It seems to be used most frequently with ActionScript 3 (Flash), but is also available in recent Mozilla/Firefox releases."
