Please help. Trying to create external xml vidoe playlist. Desperate!

Question

I was given an assignment to  create and external video playlist using an xml file.  I have never used  flash before, know nothing about encoding and all that was given to the  class in terms of instuctions was a short tutorial that has no  resources for troubleshooting.  We were given everything; the external  playlist file equipped with the video skin, the video list, actionscript  that loads the xml and the xml file.  We were told that all we need to  do is change the names of the videos in the xml file to match the names  of our videos.  I did that.  We were also told we needed to "name  target", but we were not informed on how to do this.  I have tried  everything, visited every tutorial and I cannot figure out how to get  this damn thing to work.  I cannot even get flash to load the xml file.  PLEASE HELP.
Here is the xml file:
<?xml version = "1.0" encoding = "i-8859-1"?>
<playlist>
<ADogWithoutABone
flvurl="ADogWithoutABone.flv"
desc="Hyper Wall First Video" />
<Highway
flvurl="Highway.flv"
desc="Hyper Wall Second Video" />
<PsychoBabble
flvurl="PsychoBabble.flv"
desc="Hyper Wall Third Video" />
<SomethingElse
flvurl="SomethingElse.flv"
desc="Hyper Wall Fourth Video" />
</playlist>
I tried putting in the entire address of the file location, but it did nothing.
Here is the actionscript in the flash file:
var xmlLoader:URLLoader = new URLLoader();
xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded);
xmlLoader.load(new URLRequest("playlistXML.xml"));
function xmlLoaded(event:Event):void {
var playlistXML:XML = new XML(event.target.data);
var item:XML;
for each(item in playlistXML.videoname) {
trace("item: "+item.attribute("flvurl").toXMLString());
myPlayList.addItem({label:item.attribute("desc").toXMLString(), data:item.attribute("flvurl").toXMLString()});
//Select the first video
myPlayList.selectedIndex = 0;
//And automatically play it
myPlayScreen.play(myPlayList.selectedItem.data);
//Add a listener to detect when new video is selected and play it
function listListener(event:Event) {
myPlayScreen.play(event.target.selectedItem.data);
myPlayList.addEventListener(Event.CHANGE, listListener);
I  tried placing the full address of the xml file in, along with the file  address of the videos, but again it did nothing.  Everything is located  in the same file, and the videos in a sub file in that file. I tried  taking out the sub file and putting all the videos in the same file, but  it did nothing.  I am sure it's something very simple, but like I said I  have NO experience with this whatsoever. I am SO lost and DESPERATELY  need help. PLEASE someone SAVE MEEEE!
Thanks

to parse your xml correctly use:
function xmlLoaded(event:Event):void {
    var playlistXML:XML=new XML(event.target.data);
    var item:XML;
    for each (item in playlistXML.children()) {
        trace("node: "+item.attribute("flvurl").toXMLString());
        myPlayList.addItem({label:item.attribute("desc").toXMLString(), data:item.attribute("flvurl").toXMLString()});
    //Select the first video
    myPlayList.selectedIndex=0;
    //And automatically play it
    myPlayScreen.play(myPlayList.selectedItem.data);
you more problems after that, though.  is myPlayList a list component?
