Openlayers xml parser and POST request

[paulmaddock]

Every time I submit the POST request I receive an XMLHttpRequest Object which has a status of 0 and a value of NULL.  My only thought is that I've entered the request incorrectly.  When I send the http request manually with the uri string it displays the xml document just fine.

function getFullURL() {
			var queryString0 = document.forms[0].lat.value;
			var queryString1 = document.forms[0].lon.value;
			
			var myData = "format=xml" + "&lat=" + encodeURIComponent(queryString0) + "&lon=" + encodeURIComponent(queryString1) + "&MaxResponse=1" + "&zoom=17" + "&accept-language=en-us" + "&addressdetails=1";
			var myCompleteURL = myURL + myData;
			return myCompleteURL;
			}
		function getMyData() {
			var queryString0 = document.forms[0].lat.value;
			var queryString1 = document.forms[0].lon.value;
			
			var myData = "format=xml" + "&lat=" + encodeURIComponent(queryString0) + "&lon=" + encodeURIComponent(queryString1) + "&MaxResponse=1" + "&zoom=17" + "&accept-language=en-us" + "&addressdetails=1";
			return myData;
		}
		function submitform() {
            //concatenate post request into single string myData
			var myCompleteURL = getFullURL();
			var myData = getMyData();
			alert(myURL);
			var theLocation = document.getElementById("docs");
			var text = document.createTextNode(myCompleteURL);
			theLocation.appendChild(text);
			
			
			//Post method with data.  Protocol for success and failure.
            OpenLayers.Request.POST({
                url: myURL,
                scope: this,
                failure: requestFailure,
                success: requestSuccess,
                //headers: {'Content-Type': 'application/xml'},
                data: myData
            });
        }
        function requestSuccess(request) {
			var format = new OpenLayers.Format.XML();
			var myCompleteURL = getFullURL();
			var myData = getMyData();
			alert(request.status);
			
			
			var doc = request.responseXML;
			var theLocation = document.getElementById("docs");
			var text = document.createTextNode("     " + doc);
			theLocation.appendChild(text);
			
			var output = format.getAttributeNS(doc,'*', '*');
			alert(output[1]);
			alert("2");
			/* THE PROBLEM HAS TO BE IN THE NAMESPACE TYPE */
			
			
			//appends the node in text form to element with id = docs in html form
			xmlOutput = format.write(doc);
			var theLocation = document.getElementById("docs");
			var text = document.createTextNode(xmlOutput);
			
			
			//theLocation.appendChild(text);
			alert("paul");
            //var output = format.getAttributeNS(;
            if (output.responseLists[0]) {
                var geometry = output.responseLists[0].features[0].geometry;
                var foundPosition = new OpenLayers.LonLat(geometry.x, geometry.y).transform(
                        new OpenLayers.Projection("EPSG:4326"),
                        map.getProjectionObject()
                        );
                map.setCenter(foundPosition, 16);
            } else {
                alert("Sorry, no address found");
            }
}
