Loading content from XML help needed, please.

Question

Hey All,
So here's my deal- I have a custom-built FLV Playback
component (with captions) and need to load the following items from
an XML file named "xml_doc.xml":
<?xml version="1.0" encoding="UTF-8"?>
<playlist id="Here's The Video" >
<vid desc="Introduction to Biological Terrorism Agents"
src="Intro.flv"
thumb="Intro.jpg"
caption="Intro.xml"
</playlist>
On the stage, here's what things are named:
-my FLVPlayback Component is named myVideo
-my thumbnail/preview image (empty movie clip) is named
myPoster
-my FLVPlaybackCaptioning Component is named captioning
So how do I get these things to all get read from the XML
document? It's easy to do it all through the FLA and hard-code the
paths, but I can't seem to figure out how to pull from the external
XML doc.
Any help would be greatly appreciated.

Answer 1

You'll need to instantiate a few classes to help with this.
The first is URLRequest:
--var myXMLRequest:URLRequest = new
URLRequest("xml_doc.xml");
The URLRequest gets loaded by a URLLoader:
--var myXMLLoader:URLLoader = new URLLoader();
Then use the .load() method of the URLLoader:
--myXMLLoader.load(myXMLRequest)
Then add an event listener to your URLLoader
--myXMLLoader.addEventListener(Event.COMPLETE, dataLoaded);
Finally create the function to work with your data
--function dataLoaded(e:Event):void {
--var myXML:XML = new XML(e.target.data);
--trace(myXML);
Looks like:
--var myXMLRequest:URLRequest = new
URLRequest("xml_doc.xml");
--var myXMLLoader:URLLoader = new URLLoader();
--myXMLLoader.load(myXMLRequest)
--myXMLLoader.addEventListener(Event.COMPLETE, dataLoaded);
--function dataLoaded(e:Event):void {
--var myXML:XML = new XML(e.target.data);
--trace(myXML);
(remove dashses, they're for readability)
