Convert XML to JSON (and back) using Javascript

I think this is the best one: Converting between XML and JSON

Be sure to read the accompanying article on the xml.com O'Reilly site, which goes into details of the problems with these conversions, which I think you will find enlightening. The fact that O'Reilly is hosting the article should indicate that Stefan's solution has merit.

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);

These answers helped me a lot to make this function:

function xml2json(xml) {  try {    var obj = {};    if (xml.children.length > 0) {      for (var i = 0; i < xml.children.length; i++) {        var item = xml.children.item(i);        var nodeName = item.nodeName;        if (typeof (obj[nodeName]) == "undefined") {          obj[nodeName] = xml2json(item);        } else {          if (typeof (obj[nodeName].push) == "undefined") {            var old = obj[nodeName];            obj[nodeName] = [];            obj[nodeName].push(old);          }          obj[nodeName].push(xml2json(item));        }      }    } else {      obj = xml.textContent;    }    return obj;  } catch (e) {      console.log(e.message);  }}

As long as you pass in a jquery dom/xml object: for me it was:

Jquery(this).find('content').eq(0)[0]

where content was the field I was storing my xml in.
