tjumyk / xmlToJson.js

Created April 8, 2013 16:51

A modified version of the xmlToJson function from http://davidwalsh.name/convert-xml-json, it removes the useless whitespace strings and extract attributes as normal properties so as to make the json simpler and tidier. Only for personal convenience, any ideas?

	// 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"] = {};
