xml加載MP3播放器時出錯

Question

加載MP3播放器時出現錯誤，這是我按Ctrl + Enter時出現的問題。

TypeError：錯誤＃1090：XML解析器失敗：元素格式錯誤。 在moviesound_fla :: MainTimeline/getsongs（） 在flash.events::EventDispatcher/dispatchEventFunction（） 在flash.events::EventDispatcher/dispatchEvent（） 在flash.net::URLLoader/onComplete（）

這是我用

<?xml version="1.0" encoding="UTF-8"?> 
<songs> 

<song atitle="Blind Willie" aurl="blind_willie.mp3" /> 

<song atitle="Wayfaring Stranger" aurl="wayfaring_stranger.mp3" /> 

<song atitle="Come, Thou Fount of Every Blessing" aurl="come_thou_fount.mp3" /> 

<song atitle="Give Me Jesus" aurl="give_me_jesus.mp3" /> 

</songs> 

</xml> 

這裏的XML是我的動作腳本

var getfile:URLLoader=new URLLoader(new URLRequest('song.xml')); 

var amountofsongs:int=0; 
var currentsong:int=0; 
var songlist:XML = new XML(); 
var sc:SoundChannel=new SoundChannel(); 

getfile.addEventListener(Event.COMPLETE, getsongs); 
n_btn.addEventListener(MouseEvent.MOUSE_DOWN,n_song); 
b_btn.addEventListener(MouseEvent.MOUSE_DOWN,b_song); 

function getsongs(e:Event):void { 
    songlist = XML(e.target.data); 
    amountofsongs = songlist.song.length()-1; 
    playsong(); 
} 

function n_song(e:MouseEvent):void { 
    currentsong++; 
    playsong(); 
} 
function b_song(e:MouseEvent):void { 
    currentsong--; 
    playsong(); 
} 

function playsong():void{ 
    sc.stop(); 
    if (currentsong>amountofsongs){ 
     currentsong=0; 
    }if (currentsong<0){ 
     currentsong=amountofsongs; 
    } 
    song_txt.text=songlist.song[currentsong].@atitle; 
    var song:Sound=new Sound(new URLRequest(songlist.song[currentsong].@url)); 
    sc=song.play(); 
    sc.addEventListener(Event.SOUND_COMPLETE,songend); 
} 
function songend(e:Event):void { 
    e.target.stop(); 
    currentsong++; 
    playsong(); 
} 

只有兩個按鈕，這是以前的（b_btn）和未來（n_btn）

此操作腳本中是否有任何錯誤，或者只有將它放在網頁上後纔有效？

一個正確的XML的文件是：

<?xml version="1.0" encoding="UTF-8"?> 
<songs> 
    <song atitle="Blind Willie" aurl="blind_willie.mp3" /> 
    <song atitle="Wayfaring Stranger" aurl="wayfaring_stranger.mp3" /> 
    <song atitle="Come, Thou Fount of Every Blessing" aurl="come_thou_fount.mp3" /> 
    <song atitle="Give Me Jesus" aurl="give_me_jesus.mp3" /> 
</songs> 

沒有必要使用</xml>
