Description:
------------
It seems empty() on simplexml 'array' elements doesn't work same way in 5.2.5 as in 5.2.3. In 5.2.5, empty() returns true even through the elements are actually present. Same code run under 5.2.3 works correctly, i.e. returning true only if the element is not present.

Workaround is replace (!empty(...)) condition with isset() and test for count(), but this is inconvenient and breaks backwards compatibility.

Reproduce code:
---------------
<?php

$str = '<?xml version="1.0" encoding="WINDOWS-1250" ?>

<config>

        <items>
                <item command="overview"/>
                <item command="deals"/>
                <item command="regions"/>
                <item command="estimations"/>
                <item command="reports"/>
                <item command="import"/>
        </items>

</config>
';

$xml = simplexml_load_string($str);

echo (empty($xml->items->item) ? "EMPTY" : "full")."\n";
echo count($xml->items->item) ."\n";


Expected result:
----------------
full
6

Actual result:
--------------
EMPTY
6
