xhrPost works differently with Firefox and IE8 - but how do I handle the response?

Question

I really don't understand why I get a different response from xhrPost with Dojo. For IE8 it works fine and the XML can be read - but in Firefox it works differently and there is no such attribute as "serverResponse.results[0].xml" - see below:

var serverResponse = dojo.xhrPost(xhrArgs);
serverResponse.results[0].xml

like you get in IE8.

Does anyone know how to handle responses properly in Firefox when using xhrPost. Cheers.

var message = '<?xml version="1.0" encoding="utf-8"?>' +
                    '<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"&gt;' +
                      '<soap12:Body>' +
                        '<MineSearch xmlns="http://localhost/"&gt;' +
                          '<x>' + inPoint.x + '</x>' +
                          '<y>' + inPoint.y + '</y>' +
                          '<buffer>' + buffer + '</buffer>' +
                        '</MineSearch>' +
                      '</soap12:Body>' +
                    '</soap12:Envelope>';




        //The parameters to pass to xhrPost, the message, and the url to send it to
        //Also, how to handle the return and callbacks.
        var xhrArgs = { url: "http://localhost/ApplicationServices.asmx?op=MineSearch",
            postData: message,
            headers: { "Content-Type": "application/soap+xml" },
            handleAs: "xml",
            sync: true,
            load: function(data) {
                dojo.byId("footer").innerHTML = "Message posted.";
            },
            error: function(error) {
                dojo.byId("footer").innerHTML = "Message error.";

            }
        }

        //Call the asynchronous xhrPost
        var serverResponse = dojo.xhrPost(xhrArgs);
        var xmldata = serverResponse.results[0].xml;
        var xmlDoc;

        if (window.DOMParser) {
            parser = new DOMParser();
            //Below is wrong somehow and the serverResponse.results[0] is probably wrong too.
            xmlDoc = parser.parseFromString(serverResponse.results[0], "text/xml");
        }
        else // Internet Explorer
        {
            xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
            xmlDoc.async = "false";
            xmlDoc.loadXML(xmldata);
        }

The return object of dojo.xhrPost is a dojo.Deferred object and the response should not be retrieved from the dojo.Deferred object.

If you specified handleAs as xml, you can get the response XML document directly in the load function by the argument data.

var xhrArgs = { url: "http://localhost/ApplicationServices.asmx?op=MineSearch",
        postData: message,
        headers: { "Content-Type": "application/soap+xml" },
        handleAs: "xml",
        sync: true,
        load: function(data) {
            //data is the XML document
        },
        error: function(error) {
            dojo.byId("footer").innerHTML = "Message error.";

        }
}
dojo.xhrPost(xhrArgs);
