Flash / XML mp3 playlist problem - Flash / Actionscript Forum

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:

Expand|Select|Wrap|Line Numbers

	<?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:

Expand|Select|Wrap|Line Numbers

	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.
