Oh, I did not see that you are requesting the event.target.data two
times... this is not a mistake, but you don't need to do this. The
mistake actually is in the fact that you are requesting a wrong
hierarchy of xml nodes for your points and thus there are no
polylines.
So instead of casting the event target data a second time, use the
above already created 'polylineXML' XML-object. Your code would be:
public function readXmlTest(event:Event):void
{
var polylinesXML:XML = new XML(event.target.data);
var polylines:XMLList = polylinesXML.polyline;
var polylinesCount:int = polylines.length();
var i:Number;
for (i=0; i < polylinesCount; i++)
{
var polylineXml:XML = polylines[i];
var line:String = polylinex...@line;
var color:String = polylinex...@color;
var latlng:Array = new Array();
var points:XMLList = polylineXml.point;
var pointsCount:int = points.length();
var a:Number;
for (a=0; a < pointsCount; a++)
{
var point:XML = points[a];
latlng.push(new LatLng(poi...@lat,
poi...@lng));
}
var poly:Polyline = new Polyline(latlng);
map.addOverlay(poly);
}
}
You may even shorten this to:
public function readXmlTest(event:Event):void
{
var polylinesXML:XML = new XML(event.target.data);
var polylines:XMLList = polylinesXML.polyline;
for each (polyline:XML in polylines)
{
var line:String = polylinex...@line; << use
this somewhere
var color:String = polylinex...@color; << use this
somewhere
var latlng:Array = new Array();
var points:XMLList = polyline.point;
for each (point:XML in points)
{
latlng.push(new LatLng(poi...@lat,
poi...@lng));
}
map.addOverlay(new Polyline(latlng));
}
}
