Hello,

just a note for people like me who encounter the problems :

<?php
foreach($xmlIterator as $x)
{
    if(
$x->hasChildren())
    {
       
//never reach
       
echo 'x : ';
       
var_dump($x->current());
    }
    if(
$xmlIterator->hasChildren())
    {
        echo
'iterator : ';
       
var_dump($x->current()); //all time null
       
var_dump($xmlIterator->current());
    }
}
?>
