ECMAScript for XML (E4X) is a programming language extension that adds native XML support to JavaScript. It does this by providing access to the XML document in a form that feels natural for ECMAScript programmers. The goal is to provide an alternative, simpler syntax for accessing XML documents than via DOM interfaces. A valid alternative to E4X is a non-native JXON algorithm.

+

E4X is standardized by Ecma International in ECMA-357 standard (currently in its second edition, December 2005).

+

E4X is implemented (at least partially) in SpiderMonkey (Gecko's JavaScript engine) and in Rhino (JavaScript engine written in Java).

+

 

+
+ Note: In Gecko 1.8 based browsers such as Firefox 1.5, E4X is already partially enabled for web page authors. To fully enable E4X, the <script> element needs to have the MIME type "text/javascript;e4x=1" (i.e. have an attribute of the form type="text/javascript;e4x=1"). The difference between the two modes is that without the "e4x=1" MIME type, any statement-level XML/HTML comment literals (<!--...-->) are ignored for backwards compatibility with the comment hiding trick, and CDATA sections (<![CDATA{{ mediawiki.external('...') }}]>) are not parsed as CDATA literals (which leads to a JS syntax error in HTML since HTML's <script> element produces an implicit CDATA section, and therefore cannot contain explicit CDATA sections). +

someone verify the above

Known bugs and limitations

+ +

Workaround:

+
var response = xmlhttprequest.responseText; // bug 270553
+response = response.replace(/^<\?xml\s+version\s*=\s*(["'])[^\1]+\1[^?]*\?>/, ""); // bug 336551
+var e4x = new XML(response);
