flex 读取xml 实现点的自定义位置高亮显示和闪烁

下面的代码实现基本的地图。用esri公司提供的为例 第2个url自己换个喜欢的图
<mx:Canvas id="canvas" width="100%" height="100%" borderStyle="solid" borderThickness="2" borderColor="#439AD7">
<esri:Map id="map" logoVisible="false" panArrowsVisible="true">
        <esri:ArcGISDynamicMapServiceLayer   url="http://server.arcgisonline.com/ArcGIS/rest/services/NPS_Physical_World_2D/MapServer"/>
<esri:ArcGISDynamicMapServiceLayer   id = "map1" url="http://server.arcgisonline.com/ArcGIS/rest/services/NPS_Physical_World_2D/MapServer"/>
       </esri:ArcGISDynamicMapServiceLayer>
    </esri:Map>
    </mx:Canvas>

下面的代码是 读取xml是的 url连接 和xml里面的第一个title的显示
  <mx:HTTPService id="myService" url="*.xml" result="resultHandler(event)" />
    <mx:Text id="txt" text="{myData.getItemAt(0).title}" />

下面是script的完整代码 实现点的自定义位置高亮显示和闪烁
private var graphicslayer:GraphicsLayer=new GraphicsLayer();
public function init():void
{
myService.send();
map.addLayer(graphicslayer);
this.map.addEventListener(ZoomEvent.ZOOM_END,mouseZ);

var t:Timer = new Timer( 500,20 );
    t.addEventListener( TimerEvent.TIMER, onTimer );
    t.start();
}
public function mouseZ(event:ZoomEvent):void
{
if(this.map1.visible == false)
{
this.map1.visible =true;
var mapPoint:MapPoint =new MapPoint();
mapPoint.x =121.123123;
mapPoint.y =31.12341;
this.map.centerAt(mapPoint);
this.map.scale = 1800000;
}
}
public function onTimer(event:Event):void
{
graphicslayer.clear();
var mapPoint:MapPoint =new MapPoint();
mapPoint.x =121.123123;
mapPoint.y =31.12341;
    var simpleMarkerS:SimpleMarkerSymbol=new SimpleMarkerSymbol();
    simpleMarkerS.color=0x00FF00;
    simpleMarkerS.size =10;
    // circle园  triangle三角 square方形 diamond菱形 cross十字 X
    simpleMarkerS.style ="circle";
    var graphics:Graphic=new Graphic();
    graphics.symbol =simpleMarkerS;
    graphics.geometry =mapPoint;
    graphicslayer.add(graphics);
   
}
[Bindable]
private var myData:ArrayCollection;

private function resultHandler(event:ResultEvent):void {
myData = event.result.books.item;

}
