 Building a kind of radio broadcast with XML
hi guys...
i´m trying to uild a kind of radio for my site, the idea is broacast from a mp3 player continuous playing but im stuck with my xml.
what i want to do is grab a xml list, and loop the files...meaning..when they achive the end go back to beginning.
The code im using till now is this:
XML:
<?xml version="1.0" encoding="iso-8859-1"?>
<musica>
<music url="mixset.mp3"/>
<music url="mixset2.mp3"/>
<music url="mixset3.mp3"/>
</musica>
Flash:
i=0;
mNumber = 0;
listaMP3 = new XML();
listaMP3.ignoreWhite = true;
listaMP3.load("playlist.xml");
listaMP3.onLoad = function ()
{
_global.songfile = [];
_global.songfile[i] = listaMP3.firstChild.childNodes[i].attributes.url;
trace(songfile[i]);
trilha = new Sound();
list = listaMP3.firstChild.childNodes;
som = list[0].attributes.url;
trilha.loadSound(som, true)
som.start(0, 0)
trilha.onSoundComplete = function (){
if (mNumber<list.length){
mNumber++
i++
_global.songfile[i] = listaMP3.firstChild.childNodes[i].attributes.url;
trace(songfile[i]);
som = list[mNumber].attributes.url;
trilha.loadSound(som, true);
}
}
}
What is happening is that it plays all 3 files but i cant get back to beginning, ive tryied conditions like "if" or "do whilhe" and i just cant do it...well..i can loops the first 2 files by inserting at the end of the code:
if (trilha.onSoundComplete) { gotoAndPlay(1) }
but this does not allows me to listten to the 3rd element of the XML list.
what shall i do?
Thank you:
Duarte V.

Let myself clear first!
Are you want to play 1 then 2 then 3 and then back to 1 and loop?
Or, play 1 and loop to 1 until user click to play for other from the list?

VERY MUCH THANKS 
it works perfectly..im not using the:
trace (list.length)
it works anyway but is it necessary?
im not using it cause i might have to grab the output data to display the names in the "radio".....
Thanks Again!

trace is for debugging purpose. I put it to show that the length is 3 of the xml node and for that you have to loop from length - 1.
One change will be a good standard in xml.
Code:
<?xml version="1.0" encoding="iso-8859-1"?>
<musica>
<music>
<musicTitle>Title 1</musicTitle>
<musicDes>Description</musicDes>
<musicURL>mp3/mixset1.mp3</musicURL>
</music>
<music>
<musicTitle>Title 2</musicTitle>
<musicDes>Description</musicDes>
<musicURL>mp3/mixset2.mp3</musicURL>
</music>
<music>
<musicTitle>Title 3</musicTitle>
<musicDes>Description</musicDes>
<musicURL>mp3/mixset3.mp3</musicURL>
</music>
