Convert XML to JSON with JavaScript

Written by David Walsh on Monday, April 4, 2011

The JavaScript

It's important to point out that Titanium's Titanium.XML.DOMDocument object implements DOM2-level structures.  Here's the magic XML to JSON code:

Copy Code

// Changes XML to JSONfunction 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].length) == "undefined") {          var old = obj[nodeName];          obj[nodeName] = [];          obj[nodeName].push(old);        }        obj[nodeName].push(xmlToJson(item));      }    }  }  return obj;};

Nice - I've been researching this recently for a similar project.
