Complete ECMA357(a.k.a. E4X) parser written in JS

[Yusuke SUZUKI]

E4X is finally removed from Firefox 21 SpiderMonkey... But E4X revives like a phoenix :)

I created the complete ECMA357, a.k.a. E4X parser on the top of Esprima harmony.

This implements *ALL* ECMA357 features. (NOT partially)

Demo shows that all examples written on ECMA357 spec are parsed correctly, such as,

    var message = <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"

           soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">

       <soap:Body>

           <m:GetLastTradePrice xmlns:m="http://mycompany.com/stocks">

              <symbol>DIS</symbol>

           </m:GetLastTradePrice>

       </soap:Body>

    </soap:Envelope>

    message.soap::Body.stock::GetLastTradePrice.symbol = "MYCO";

And it also supports SpiderMonkey extension such as function namespace.

Demonstration is here. http://constellation.github.io/demo/e4x/index.html

I hope that this will help someone that loves E4X.
