Thanks Darek,
it works perfectly...
Here is the final code for everyone who want´s to read polylines from
XML:
getPolyline();
public function getPolyline():void
{
var xmlString:URLRequest = new URLRequest("polyline.php");
var xmlLoader:URLLoader = new URLLoader(xmlString);
xmlLoader.addEventListener("complete", readXmlPolyline);
}
public function readXmlPolyline(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 color:Number = 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);
var options:PolylineOptions = new
PolylineOptions({strokeStyle:{color: color, thickness: 7, alpha:
1.0}});
poly.setOptions(options);
map.addOverlay(poly);
}
}
Greetings AK
