how to do foreach with another foreach

[bcragi]

I am trying to create a playlist manager and running into problems. The playlist is in xml and I am able to create tracklists, but what I want is to put tracklists within an album, and then add another album with tracklist. So the xml output is like this:

<?xml version="1.0" ?>
<playlist>
<albums>
<album id="1">
<tracks>
<track></track>
<track></track>
<track></track>
</tracks>
</album>

<album id="2">
<tracks>
<track></track>
<track></track>
<track></track>
</tracks>
</album>
</albums>
</playlist>

So far I am able to do a foreach loop for the <tracks>, but I can't find any info whether I can put that loop inside another larger foreach loop which controls the album info, or should I be creating another kind of loop within a loop structure?

any help in the logic is appreciated...
thanks!

A foreach() within a foreach() is perfectly acceptable.

$range1 = range(1, 10);
$range2 = range("a", "z");

 foreach($range1 as $number)
  foreach($range2 as $letter)
   echo $number.$letter." ";

 // Prints 1a 2a 3a 4a ... 10a 1b 2b 3b ... 10b ... 1z ... 10z
