Function to convert XML to JSON

xmlToJson.js

// Changes XML to JSON
// Modified version from here: http://davidwalsh.name/convert-xml-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 just one text node inside
	if (xml.hasChildNodes() && xml.childNodes.length === 1 && xml.childNodes[0].nodeType === 3) {
		obj = xml.childNodes[0].nodeValue;
	}
	else 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;
}

I love you.

Hi,
First thank you for the code ;)

Maybe an update that could help.
line.23 : Just add this && !obj["@attributes"] to keep attributes when node is type === 3 (text)

Hi,

Need a help urgently.
I am getting an error as "xml.hasChildNodes is not a function".

Will be very thankful if you could help me.

Having the same issue as @charith93.

Hello,
I have the same issue as @charith93 & @salshyn, someone can help us please?

Thanks.

@charith93 @LuceroGera @salshyn my guess is you are passing a string instead of a XML-DOM obj. Try this instead,

var xml = "The XML as String";
var xmlDOM = new DOMParser().parseFromString(xml, 'text/xml');

and then,

xmlToJson(xmlDOM);
