動作腳本按出現的順序對xml Feed進行排序

Question

我已經修改了以下腳本，我想刪除隨機腳本，並改爲使其顯示爲xml訂閱源的順序，但我試過了，但沒有任何效果爲了我。

我需要修改這一行：_global.song_nr = random(songfile.length);

完整劇本

playlist.onLoad = function(success) { 
    if (success) { 
     _global.songname = []; 
     _global.songband = []; 
     _global.songimg = []; 
     _global.songdate = []; 
     _global.songfile = []; 
     for (var i = 0; i<playlist.firstChild.childNodes.length; i++) { 
      _global.songname[i] = playlist.firstChild.childNodes[i].attributes.name; 
      _global.songband[i] = playlist.firstChild.childNodes[i].attributes.artist; 
      _global.songimg[i] = playlist.firstChild.childNodes[i].attributes.img; 
      _global.songdate[i] = playlist.firstChild.childNodes[i].attributes.date; 
      _global.songfile[i] = playlist.firstChild.childNodes[i].attributes.file; 
      trace(songname[i]+" "+songband[i]+" "+songimg[i]+" "+songdate[i]+" "+songfile[i]); 
     } 
    } 
    _root.createEmptyMovieClip("sound_mc", 1); 
    _root.sound_mc.sound_obj = new Sound(); 
    _global.song_nr = random(songfile.length); 
    _root.sound_mc.songStarter(songfile[song_nr], songname[song_nr], songband[song_nr], songimg[song_nr], songdate[song_nr]); 
};

感謝@GeorgeProfenza這個作品 - 簡單:)

_global.song_nr = 0;
