} } any ideas? 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);
