Loading XML in Flash AS3

1. Create the xml file, as shown below
2. In the flash file drag a datagrid component from the components panel.
3. Create new instance of the URLLoader class which loads the xml file.
4. xml file is passed to the url inside the URLRequest object.
5. Then add an addEventListener to know when the xml file is completely loaded, we register a COMPLETE event and have it call a function.
In the function we access loaded data through URLLoader ‘s data property.and assign this to XML object.
difference between XMLList and array is that in XMLList length()  is a property.
6. Populate any data driven component including a data grid we have to create an instance of a DataProvider class .
Each time the loop runs xml data is added inside of the griddata provider using addItem({name:value})shorthand notation to create a generic object, name value pairs seperated by a “: ” this data is then set to the datagrid. Freelance flash  developer Bangalore

Loading XML in Flash AS3 code goes here:

var imagesXML:XML;
var xmlLoader:URLLoader = new URLLoader();
xmlLoader.load(new URLRequest(“picts.xml”));
xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded);

function xmlLoaded(evt:Event):void
{
imagesXML = new XML(xmlLoader.data);
var componentProvider:DataProvider = new DataProvider();
for(var i:uint = 0; i < imagesXML.animal.length(); i++)
{
componentProvider.addItem({name:imagesXML.animal.name[i],description:imagesXML.animal.description[i]});
}
grid.dataProvider = componentProvider;

}
grid here is the instance name of datagrid component on stage. Make sure flash has imported
import fl.data.DataProvider;

The xml file is as follows:

<animals>

<name>bunny</name>
