Xml2Json in JavaScript

Here is the simple function via DWB (DavidWalshBlog). You can use to convert XML to JSON in your JavaScript code.

// Changes XML to JSON
function xmlToJson(xml) {
 
 // Create the return object
 var obj = {};

 if (xml.nodeType == 1) { // element
  // do attributes
  if (xml.attributes.length > 0) {
  obj["@attributes"] = {};
   for (var j = 0; j < xml.attributes.length; j++) {
    var attribute = xml.attributes.item(j);
    obj["@attributes"][attribute.nodeName] = attribute.nodeValue;
   }
  }
 } else if (xml.nodeType == 3) { // text
  obj = xml.nodeValue;
 }

 // do children
 if (xml.hasChildNodes()) {
  for(var i = 0; i < xml.childNodes.length; i++) {
   var item = xml.childNodes.item(i);
   var nodeName = item.nodeName;
   if (typeof(obj[nodeName]) == "undefined") {
    obj[nodeName] = xmlToJson(item);
   } else {
    if (typeof(obj[nodeName].push) == "undefined") {
     var old = obj[nodeName];
     obj[nodeName] = [];
     obj[nodeName].push(old);
    }
    obj[nodeName].push(xmlToJson(item));
   }
  }
 }
 return obj;
};
