A few days ago Dave over at the WebGraphics blog posted about how to parse a string into a DOM tree for Safari.

I commented “How about implementing the DOMParser object in js?” and before I knew it I did it myself and adding IE compatibility on the way:

if (typeof DOMParser == "undefined") {
   DOMParser = function () {}
	
   DOMParser.prototype.parseFromString = function (str, contentType) {
      if (typeof ActiveXObject != "undefined") {
         var d = new ActiveXObject("MSXML.DomDocument");
         d.loadXML(str);
         return d;
      } else if (typeof XMLHttpRequest != "undefined") {
         var req = new XMLHttpRequest;
         req.open("GET", "data:" + (contentType || "application/xml") +
                         ";charset=utf-8," + encodeURIComponent(str), false);
         if (req.overrideMimeType) {
            req.overrideMimeType(contentType);
         }
         req.send(null);
         return req.responseXML;
      }
   }
}

Both Opera and Mozilla already have this object
