success isn't successful, it just gets back the xml if successful or in the case of firefox, it seems to get a special parsererror (formatted as xml)!
I've removed all callbacks except complete, I have to do a lot of browser specific code to determine if the xml is malformed or the file is missing.
the final case is the actual success.
this is what I have so far:

Yes, I think so. Or the success callback. The reason is, that the
response has been successfully delivered, just with ill-formed XML.
You may need a try/catch, but I don't know how browsers handle
ill-formed XML, e.g. if you can catch that error...

now I have this for the browsers I use, I wonder what IE would whine about!
    var surveyComplete = function(xrh, status){
        var xml = xrh.responseXML
        if (status!="success")
           
form.html("<h1>" + status.toUpperCase() + " requesting:<a href='" + url + "'>" + url +"</a></h1>")
                .append("<pre>" +
xrh.responseText + "</pre>")
        else if (!xml) //safari webkit
            form.text(xrh.responseText).wrap("<pre></pre>")
                .prepend("<h1> broken xml:<a href='" + url + "'>" + url +"</a> </h1>")
        else if (xml.hasChildNodes && !xml.hasChildNodes()) // opera
            form.text(xrh.responseText).wrap("<pre></pre>")
                .prepend("<h1> broken xml:<a href='" + url + "'>" + url +"</a> </h1>")
        else if (xml.firstChild.nodeName == "parsererror") //firefox
            form.text(xrh.responseText).wrap("<pre></pre>")
                .prepend("<h1> broken xml:<a href='" + url + "'>" + url +"</a> </h1>"+ $.xml(xml))
        else
            surveyProcess(xml)
    }
    $.ajax({url:url,datatype:'xml',complete:surveyComplete})
