convert JSON object to XML using javascript

Question

I want to convert a JSON object to a XML String and I can't figure a proper way to do it. I've found a neat little jQuery plugin called json2xml at https://gist.github.com/c4milo/3738875 but it doesn't escape the data.

How can I escape the data properly so that the browser's XML parser will work?

You can try this small library http://code.google.com/p/x2js/

There is no unique way of doing this. You should be using XML with a schema only, and JSON doesn't have such a schema. Any such transformation when done naively is likely to break.

Why don't you just use XML or JSON consequently?

The conversion is just for using the XML with XSLT ... not my idea. The server-side scripts only output JSON and I have to somehow convert the response in a valid XML. Is this doable?

Of course it is doable. XML is not that hard to produce, in particular when you have a DOM implementation available (I'd avoid producing a string just to feed it into a parser once). However, I would not use an approach such as the one on the website you gave, but actually try to do a /semantic/ transformation. You want the resulting XML to be valid according so some schema, after all.

You can use the external js available by google named x2js.js

You can see the demo over here.

you can use this function in your code to convert JSON to XML in js

var json2xml = function (o) {

            var tab = "\t";
            var toXml = function (v, name, ind) {
                var xml = "";
                if (v instanceof Array) {
                    for (var i = 0, n = v.length; i < n; i++)
                        xml += ind + toXml(v[i], name, ind + "\t") + "\n";
                }
                else if (typeof (v) == "object") {
                    var hasChild = false;
                    xml += ind + "<" + name;
                    for (var m in v) {
                        if (m.charAt(0) == "@")
                            xml += " " + m.substr(1) + "=\"" + v[m].toString() + "\"";
                        else
                            hasChild = true;
                    }
                    xml += hasChild ? ">" : "/>";
                    if (hasChild) {
                        for (var m in v) {
                            if (m == "#text")
                                xml += v[m];
                            else if (m == "#cdata")
                                xml += "<![CDATA[" + v[m] + "]]>";
                            else if (m.charAt(0) != "@")
                                xml += toXml(v[m], m, ind + "\t");
                        }
                        xml += (xml.charAt(xml.length - 1) == "\n" ? ind : "") + "</" + name + ">";
                    }
                }
                else {
                    xml += ind + "<" + name + ">" + v.toString() + "</" + name + ">";
                }
            }
            return xml;
        };

you get XML DOM in return, which in return you need to serialize

so in the main

            var xmlDOM = json2xml(eval(jsonObj));
            var oSerializer = new XMLSerializer();
            var sXML = oSerializer.serializeToString(xmlDOM);
