Description:
------------
We should be able to use normal array iteration 
techniques when going through such pseudoarray 
structures in simplexml elements, right?

Reproduce code:
---------------
$xml = simplexml_load_string(
'<a>
 <b></b>
 <b></b>
 <b></b>
</a>');

while(list($foo, $bar) = each($xml->b)) {
  echo '"' , $foo , '" - "', $bar , '"' , chr(10);
}

--OR--

for($i = 0; $i < count($xml->b); ++$i) {
  echo '"' , $i , '" - "', $xml->b[$i] , '"' , chr(10);
}

Expected result:
----------------
[3 lines of output]

--OR--

"0" - ""
"1" - ""
"2" - ""

Actual result:
--------------
[no output]

--OR--

"0" - ""
