How to convert string to XML object in JavaScript?

Question

I am aware of this question already existing, but it has given me no luck.

I have an application which loads a physicial XML document via the following method:

jQuery.ajax({     type: "GET",     url: fileName,     dataType: "xml",     success: function (data) {         // etc...     } }); 

I parse the XML and convert it into a string which is saved into a variable so that it can easily be stored in a database. How can I now convert the data in this variable back into an XML object so that it can be parsed as such?

Non-jQuery version:

var parseXml;  if (window.DOMParser) {     parseXml = function(xmlStr) {         return ( new window.DOMParser() ).parseFromString(xmlStr, "text/xml");     }; } else if (typeof window.ActiveXObject != "undefined" && new window.ActiveXObject("Microsoft.XMLDOM")) {     parseXml = function(xmlStr) {         var xmlDoc = new window.ActiveXObject("Microsoft.XMLDOM");         xmlDoc.async = "false";         xmlDoc.loadXML(xmlStr);         return xmlDoc;     }; } else {     parseXml = function() { return null; } }  var xmlDoc = parseXml("<foo>Stuff</foo>"); if (xmlDoc) {     window.alert(xmlDoc.documentElement.nodeName); } 

Since jQuery 1.5, you can use jQuery.parseXML(), which works in exactly the same way as the above code:

var xmlDoc = jQuery.parseXML("<foo>Stuff</foo>"); if (xmlDoc) {     window.alert(xmlDoc.documentElement.nodeName); }
