FYI yes. That is about right.
This is what I have done:
var xml = GXml.parse(request.responseText);
idD = xml.documentElement.getElementsByTagName("data_id");
latD = xml.documentElement.getElementsByTagName("latitude");
lonD = xml.documentElement.getElementsByTagName("longitude");
for (var i = 0; i < latD.length; i++) {
lat = latD[i].childNodes[0].nodeValue;
lon = lonD[i].childNodes[0].nodeValue;
id = idD[i].childNodes[0].nodeValue;
// Do some processing here
}
