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());
}
}
?>
