From the Action Script:

//------------------------------------------------------------
// Define a text field for displaying the XML's data.
// The way that the text field is defined here, a vertical scroll bar
// does not appear, but you can nevertheless scroll down using down
// arrow key, page down key, or mouse wheel:

   var myTextField:TextField = new TextField();
   myTextField.width = 400;
   myTextField.border = true;
	 myTextField.background = true;
	 myTextField.backgroundColor = 0xffffff;
   myTextField.height = 300;
	 myTextField.x = 20;
	 myTextField.y = 20;
   myTextField.wordWrap = true;
   myTextField.multiline = true;	 
	 myTextField.mouseWheelEnabled = true;
   addChild(myTextField);


//------------------------------------------------------------
// Indicate the location of the external XML file:

   var myXMLFile:URLRequest = new URLRequest("as3_myxml1.xml");

	 
//------------------------------------------------------------
// Load the external XML file into Flash:

   var myXMLLoader:URLLoader = new URLLoader();
   myXMLLoader.load(myXMLFile);

// This does the same thing in one line of code: 
// var myXMLLoader:URLLoader = new URLLoader(myXMLFile);

   myXMLLoader.addEventListener(Event.COMPLETE, runThisAfterXMLLoads);


//------------------------------------------------------------
// After the XML file is done loading, display data from it: 

function runThisAfterXMLLoads(myEvent:Event)
{
	var myXML = XML(myEvent.target.data);

	myTextField.text = myXML.introductory_comment + "\n";	
	myTextField.text = myXML.image.photographer + "\n"; 
	myTextField.appendText(myXML.colors.color[1] + "\n"); 
	myTextField.appendText(myXML.colors.color[1].@artist_primary + "\n"); 
	
	
//------------------------------------------------------------
// Loop through and display each element: 
   			
	 for each(var elements:XML in myXML.*)
	 {
		 if(elements.*.length() <= 1) // for top level elements
		 {
			 myTextField.appendText("type 1: " + elements.name() + ": " + elements + "\n");
		 }
		 else // for elements within other elements ("level 2" - Won't work for "level 3") 
		 {
			for each(var info:XML in elements.*)
			{
				myTextField.appendText("type 2: " + info.name() + ": " + info + "\n");
			}
		}
	 }
	 
} // end of function runThisAfterXMLLoads
