Creating dynamic XML without String var ?

Question

Hi all...
I am trying to create a XML to use it in a DataGrid as a
DataProvider... So far I was able to do it but only using a String
variable, is there any othe way to do it? I found/think there is
another way but i'm kinda lost on this subject... Here is how im
doing it (more or less):
private var dataPlaylist : XML;
private var xml : String = new String();
xml += ' <music>\n';
xml += ' <artist>' + player.id3.artist +
'</artist>\n';
xml += ' <track>' + player.id3.songName +
'</track>\n';
xml += ' <title>' + player.id3.title +
'</title>\n';
xml += ' <album>' + player.id3.album +
'</album>\n';
xml += ' <time>' + player.length + '</time>\n';
xml += ' </music>\n';
dataPlaylist = XML(xml);
playlist.dataProvider = dataPlaylist.musica;

It's better to read the entire XML documentation located one
level up:
http://livedocs.macromedia.com/flex/2/docs/00001910.html
For your case, you can actually do this:
dataPlayList: XML =
<music>
<artist>{player.id3.artist}</artist>
<track>{player.id3.songName}</track>
</music>;
Note the use of curly braces {} to embed variables inside
your XML. There's a lot more you can do with XML as well. It's in
the docs.
