Sorry, for clarity, I meant something like the following:
function InitMap()
{
GDownloadUrl("data.xml", CheckDataAndResponse);
alert(markerdata);
}
function CheckDataAndResponse(stringdata, responseCode)
{
//alert("Der R�ckgabewert war : "+responseCode)
alert(stringdata);
markerdata = stringdata;
markers = parseMarkerData();
CalculateCenterAndBounds();
DrawMarkers();
alert(markerdata);
}
