The answer is simple, everybody else seems to have missed it. foreach()
makes a copy of the array before working on it. Changes made to
$oneTable would obviously never affect the original. You're just
unsetting a temporary variable that's going to be overwritten next time
through the loop anyhow.
You should have better luck with this code:
$xmlDatabase = new SimpleXMLElement($myXML);
foreach ($xmlDatabase as $key => $oneTable)
fwiw, In php5 you can do something like:
foreach ($xmlDatabase as $key => &$oneTable)
//note the & ------------------^^^^
unset($oneTable);
