xml playlist id3 for flash and how to make one and play info.

I am currently messing around with a lil bit of code. never used xml b4. here it is

var tracklist = new Array ();
var mp3List = new XML ();
mp3List.ignoreWhite = true;
mp3List.onLoad = createPlayList;
mp3List.load ("playlist.xml");
function createPlayList (success)
{
 if (!success)
 {
   return;
 }
 var topLevel = null;
 for (i = 0; i <= this.childNodes.length; i++)
 {
   if (this.childNodes[i].nodeValue == null &&
       this.childNodes[i].nodeName == "playlist")
   {
     topLevel = this.childNodes[i];
     break;
   }
 }
 if (topLevel != null)
 {
   for (i = 0; i <= topLevel.childNodes.length; i++)
   {
     if (topLevel.childNodes[i].nodeName == "mp3file")
     {
       var track =
           topLevel.childNodes[i].attributes["track"];
       _root.tracklist.push (track);
     }
   }
 }
}
function randomBetween (a, b)
{
 return Math.min (a, b) + random (Math.abs (a - b) + 1);
}
function playTrack ()
{
 var track = _root.track;
 if (track.getBytesLoaded () == track.getBytesTotal () &&
     track.duration > 0)
 {
   clearInterval (_root.checkLoaded);
   trackID3Info.text = "";
   trackID3Info.text += "Title: " + track.id3.songname +
       newline;
   trackID3Info.text += "Artist: " + track.id3.artist +
       newline;
   trackID3Info.text += "Album: " + track.id3.album +
       newline;
   trackID3Info.text += "Year: " + track.id3.year + newline;
   trackID3Info.text += "Comments: " + track.id3.comment +
       newline;
 }
}
randomPlayer.onPress = function ()
{
 stopAllSounds ();
 var trackNo = randomBetween (0, trackInfo.length - 1);
 var track = new Sound ();
 track.onID3 = function ()
 {
   trackID3Info.text = "";
   trackID3Info.text += "Title: " + track.id3.TIT2 + newline;
   trackID3Info.text += "Artist: " + track.id3.TPE1 + newline;
   trackID3Info.text += "Album: " + track.id3.TALB + newline;
   trackID3Info.text += "Year: " + track.id3.TYER + newline;
   trackID3Info.text += "Comments: " + track.id3.COMM +
       newline;
 };
 track.loadSound (tracklist[trackNo], true);
};

It loads up a mp3 from xml then gets id3.

I would like to know what I should be doing from here to get it to play. the mc has 3 buttons, a dynamic text box and a background. buttons are forwards backwards and play. if you can complete this please let me know. graphics can be generic. Thanks alot.

500 points goes out to the person who gives me back a working result using the above information.!

Can you add an extract of playlist.xml that we can look at too?

Hi,
Here is your solution.

This works perfectly, I tested it out as well.

//-----------------------------------------------------
//-----------------------------------------------------

var tracklist = new Array ();
var track ="";
var mp3List = new XML ();
mp3List.ignoreWhite = true;
mp3List.onLoad = createPlayList;
mp3List.load ("playlist.xml");
function createPlayList (success)
{
 if (!success)
 {
   return;
 }
 var topLevel = null;
 trace("CHILD: "+this.childNodes.length);
 for (i = 0; i <= this.childNodes.length; i++)
 {
   if (this.childNodes[i].nodeValue == null &&
       this.childNodes[i].nodeName == "playlist")
   {
     topLevel = this.childNodes[i];
       trace("testing"+topLevel);
      
     break;
   }
 }
 if (topLevel != null)
 {
       trace("TOPLEVEL: "+topLevel.childNodes.length);
      
   for (i = 0; i <= topLevel.childNodes.length; i++)
   {
     if (topLevel.childNodes[i].nodeName == "mp3file")
     {
       
           var track = topLevel.childNodes[i].attributes["track"];
               trace("THIS IS PROBLEM: "+topLevel.childNodes[i].attributes["track"]);
                   _root.tracklist.push (track);
     }
      
      // trace("sajid:"+_root.tracklist);
   }
 }
 trace(tracklist);
}
function randomBetween (a, b)
{
 return Math.min (a, b) + random (Math.abs (a - b) + 1);
}
function playTrack ()
{
 var track = _root.track;
 trace("THIS IS TRACK: "+track);
 if (track.getBytesLoaded () == track.getBytesTotal () &&
     track.duration > 0)
 {
   clearInterval (_root.checkLoaded);
   trackID3Info.text = "";
   trackID3Info.text += "Title: " + track.id3.songname +
       newline;
   trackID3Info.text += "Artist: " + track.id3.artist +
       newline;
   trackID3Info.text += "Album: " + track.id3.album +
       newline;
   trackID3Info.text += "Year: " + track.id3.year + newline;
   trackID3Info.text += "Comments: " + track.id3.comment +
       newline;
 }
}
randomPlayer.onPress = function ()
{
 stopAllSounds ();
 var trackNo = randomBetween (0, tracklist.length - 1);
 trace("rand Tracn No: "+trackNo);
 var track = new Sound ();
 track.onID3 = function ()
 {
       trace("ON ID# CALLED");
   trackID3Info.text = "";
   trackID3Info.text += "Title: " + track.id3.TIT2 + newline;
   trackID3Info.text += "Artist: " + track.id3.TPE1 + newline;
   trackID3Info.text += "Album: " + track.id3.TALB + newline;
   trackID3Info.text += "Year: " + track.id3.TYER + newline;
   trackID3Info.text += "Comments: " + track.id3.COMM +
       newline;
      trace("Album: " + track.id3.TALB + newline);
 };
 track.loadSound (tracklist[trackNo], true);
 
};

//-----------------------------------------------------
//-----------------------------------------------------

There was a problem with "trackInfo.length"

trackInfo is not getting defined anywhere, actually it should have been, "tracklist.length"

Copy my code into your timeline and then place a movieclip on stage called "randomPlayer" and bingo :)

great that part works. how do you get it to go back a song or forward a song though using that method? if you can do that for me it would be very appreciated. basically like I originally said I have a back a song button and a forward a song button.

Ok replace the code i gave earlier with this:

var tracklist = new Array ();

function randomBetween (a, b)

randomPlayer.onPress = function ()

function loadSong(tNo){
      var track = new Sound ();

      } else {
            _root.nextPlayer.enabled=false;
      }
}

//------------------------------------------------

I added two more functions called:

playNext()
and
playPrev()

Call these functions to move to next or previous songs.

You can call then on button actions like this:

on(release){
         _root.playNext();
}

or

on(release){
         _root.playPrev();
}

now there is only one problem with this. if I start it up it will continue to play the mp3 that was playing b4 and play the next one at the same time. I tried doing a track.sound.stop();

but it still plays. Any ideas?

ssdesignCommented:
On my cmoputer it does not play the previous song. Because when you loadSound, it should automatically unload the first one.

I will see what i can figure out more here.

Hi, Any success? Let me know where you are stuck and we can resolve it.

virtexAuthor Commented:
none, it still plays the second one over the first one. If it is possible could you replace the random with just a straight play and on hit again stop then use the 2 other buttons to play one forward or one backward?

Please let me know. seems it isnt unloading it still.

Don't accept this as an answer - I'm just making a comment...

Can't you just stop the sound with stopAllSounds();?

virtexAuthor Commented:
yay!, that actually worked,
on(release){
       stopAllSounds();
       _root.playPrev();
}

I will give you some points for that still lol
I forgot all about that.
