How to load xml item one at a time as3

Question

Flash AS3:

Does anyone know how to load items one at a time instead of loading in loop at a normal process using AS3? I'm having problem with overwritten value.

I couldn't make that work, it's always overwritten the last value.I tried to use the dictionary and though it will help to resolve my problem...

I want to be able for EACH button when I clicked it displays the visibility of my markers.

private function handleMarkers(event:CustomEventCenter):void
 {
  // Get items info from custom dispatcher
  var nom  = event._name.nom;
  ...

  var tabMarkerID:Array  = new Array();

  // Defined positions for button
  var xPos = 20;
  var yPos = 0;

  // Store the right markerID into each index separated
  if (event._name.markerID == '01') {
   tabMarkerID[0] = event._name.markerID;
  } else if (event._name.markerID == '05') {
   tabMarkerID[1] = event._name.markerID;
  }

  // Create a dictionary 
  var dict:Dictionary = new Dictionary(); 

  // Create arrondissement objects for 14 available markers
  var arrond1:Object = new Object();
  var arrond2:Object = new Object();

  dict[arrond1] = tabMarkerID[0];
  dict[arrond2] = tabMarkerID[1];

  for (var i=0;i<2;i++) 
  {
   pointRepere = new PointRepere();
   for (var item:Object in dict)
   {
    if (dict[item] != undefined) {   
     pointRepere.name = String(dict[item]); // here the issue
     pointRepere.x = xPos;
     pointRepere.y = yPos;
     yPos += i*20 + 40;
     pointRepere.buttonMode = true;

     addChild(pointRepere);
     createMarkers(dict[item], nom);
     pointRepere.addEventListener(MouseEvent.CLICK, handlePointClicked);
    }
   }
  }

 }


 private function handlePointClicked(event:MouseEvent):void
 {
  trace("Name: "+event.target.name);

  displayMarkerType(event.target.name);
 }


 private function displayMarkerType(id:String):void
 {
  for (var i=0; i< _marker.tabArrondMarker[id].markers.length; i++)
  {
   var marker:Marker = _marker.tabArrondMarker[id].markers[i];
   (!marker.visible) ? marker.visible = true : marker.visible = false; 
  }
 }

Answer 1

You can load them all, and then reference them by their index. Like

xmlData.YourChildNodeName[0]

Where the 0 is the index number. This will just pull back the first child node by that name.

Answer 2

It seems like you'd want to lazy load your xml files - you'd need to construct a loop that runs based on an array of the items you want to load - here is an example of how you could do that:

private var Array:list;
private var int:count = 0;

private function init()void
{
     list = {"one.xml","two.xml","three.xml"};
     loadXML();
}

private function loadXML():void
{
     //create and init your loader
     var loader:URLLoader = new URLLoader(new URLRequest(list[count]));
     loader.addEventListener(Event.COMPLETE, completeHandler);
     loader.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
     loader.load();
}

private function completeHandler(e:Event):void
{
     //Logic here to handle the loaded xml
     continueLoad();
}

private function ioErrorHandler(e:IOErrorEvent):void
{
     //Logic here to handle the error
    continueLoad();
}

private function continueLoad():void
{
     if(count < list.length){
          count++;
          loadXML();
     }else{
          //Some logic here to do something else after all of your files have been loaded
     }
}

I just this threw this together here so you may need to fix a thing or two but you see the gist - it's a loop that executes only after each individual file has been loaded as opposed to just throwing it all in a for loop and having it execute and subsequently grind and then crash.

Hope this helps!
