Hey,
Here's how I parsed my XML file after it was finished and loaded
completely.
function onMapReady(event:Event):void {
getXML();
}
function getXML():void {
xmlLoader.load(new URLRequest("datafile.xml"));
xmlLoader.addEventListener(Event.COMPLETE, loadXML);
}
function loadXML(event:Event):void {
try {
marketData = XML(xmlLoader.data);
//trace (marketData);
parseData(marketData);
} catch (e:TypeError) {
trace("Could not parse the XML");
trace(e.message);
}
}
function parseData(marketInput:XML):void {
var marketCount:int = marketInput.market.length();
var i:Number;
for (i=0; i < marketCount; i++) {
var marketLocation:String =
marketInput.market[i].MarketLocation.text();
var lat:Number =
Number(marketinput.market[i].marketlocati...@lat);
var lng:Number =
Number(marketinput.market[i].marketlocati...@lng);
var marketMarker:Marker = createMarker(lat,lng,marketLocation);
map.addOverlay(marketMarker);
}
}
function createMarker(lat:Number,lng:Number,marketName:String):Marker
{
var markerOp:MarkerOptions = new MarkerOptions({
clickable : true,
tooltip : marketName,
hasShadow : false,
draggable : false,
iconAlignment: MarkerOptions.ALIGN_HORIZONTAL_CENTER |
MarkerOptions.ALIGN_BOTTOM
});
var marker:Marker = new Marker(new LatLng(lat,lng), markerOp);
return marker;
}
