Flash / XML mp3 playlist problem

[jiwas78]

Hey there.
I am learning XML and Actionscript.
I have a problem with getting my XML data to load when my SWF is in an HTML page in a browser. When I open the SWF on it's own whether in Flash Player or browser, my playlist of songs comes up. But in the HTML page it's a no go. Here is what my XML looks like:

<?xml version="1.0" ?>
<playlist>
    <song title="Alliance" artist="Jack Hammer & B Mac" src="../content/music/Alliance.mp3" />
    <song title="Black Friday" artist="King Gregor" src="../content/music/BlackFriday.mp3" />
    <song title="A Dangerous Man" artist="Jack Hammer" src="../content/music/DangerousMan.mp3" />
</playlist>

And my actionscript, which admittedly I did copy and paste from a tutorial and have little idea of how it all works, I just know that it doesn't:

XMLNode.prototype.moveBefore = function(beforeNode){
    if (this == beforeNode) return (0);
    beforeNode.parentNode.insertBefore( this.cloneNode(true), beforeNode);
    this.removeNode();
}
Clamp = function(min, n, max){
    if (n<min) return min;
    if (n>max) return max;
    return n;
}
 
 
 
var song_spacing = 20;
var over_node;
GenerateSongListing = function(playlist_xml, target_mc){
 
    target_mc = target_mc.createEmptyMovieClip("list_mc",1);
 
    var songs = playlist_xml.firstChild.childNodes;
    for (var i=0; i<songs.length; i++){
        var song_mc = target_mc.attachMovie("song", "song"+i, i);
        song_mc._y = i*song_spacing;
 
        song_mc.node = songs[i];
        song_mc.title_txt.text = songs[i].attributes.title;
        song_mc.moved = false;
 
        song_mc.select_btn.onPress = function(){
            this._parent.onMouseMove = function(){
                if (!this.moved){
                    dragline_mc._visible = true;
                    dragline_mc._y = playlist_mc._y + this._y;
                    highlight_mc._visible = true;
                    highlight_mc._y = playlist_mc._y + this._y;
                    this.moved = true;
                }
            }
        }
 
        song_mc.select_btn.onDragOver = function(){
            over_node = this._parent.node;
            dragline_mc._y = playlist_mc._y + this._parent._y;
        }
 
        song_mc.onMouseUp = function(){
            if (this.onMouseMove){
                delete this.onMouseMove;
                dragline_mc._visible = false;
                highlight_mc._visible = false;
                if (this.moved){
                    this.node.moveBefore(over_node);
                    GenerateSongListing(playlist_xml, playlist_mc);
                }
            }
        }
 
        song_mc.select_btn.onRelease = function(){
            if (!this._parent.moved){
                SetSong(this._parent.node);
            }
        }
 
    }
}
 
 
var playlist_xml = new XML();
playlist_xml.contentType = "text/xml";
playlist_xml.ignoreWhite = true;
playlist_xml.onLoad = function(success){
    if (success){
        GenerateSongListing(this, playlist_mc);
    }else trace("Error loading XML file"); // no success?  trace error (wont be seen on web)
}
playlist_xml.load("../xml/playlist.xml");
 
dragline_mc._visible = false;
highlight_mc._visible = false;
 

I'm sure it's just a simple issue. Something that I'm not aware of or haven't done properly. I'm a total newbie with XML and Actionscript and have tried most everything I could think of but so far no answers. Can anyone help?

Cheers.

Jack.
