Convert XML to JSON (and back) using Javascript

Question

How would you convert from XML to JSON and then back to XML?

The following tools work quite well, but aren\'t completely consistent:

• xml2json

Answer 1

https://github.com/abdmob/x2js - my own library (updated URL from http://code.google.com/p/x2js/):

This library provides XML to JSON (JavaScript Objects) and vice versa javascript conversion functions. The library is very small and doesn't require any other additional libraries.

API functions

• new X2JS() - to create your instance to access all library functionality. Also you could specify optional configuration options here
• X2JS.xml2json - Convert XML specified as DOM Object to JSON
• X2JS.json2xml - Convert JSON to XML DOM Object
• X2JS.xml_str2json - Convert XML specified as string to JSON
• X2JS.json2xml_str - Convert JSON to XML string

Online Demo on http://jsfiddle.net/abdmob/gkxucxrj/1/

var x2js = new X2JS();
function convertXml2JSon() {
    $("#jsonArea").val(JSON.stringify(x2js.xml_str2json($("#xmlArea").val())));
}

function convertJSon2XML() {
    $("#xmlArea").val(x2js.json2xml_str($.parseJSON($("#jsonArea").val())));
}

convertXml2JSon();
convertJSon2XML();
$("#convertToJsonBtn").click(convertXml2JSon);
$("#convertToXmlBtn").click(convertJSon2XML);
