The problem is with your removeChild method.
This error is a result of:
Raised if oldnode is not a child of this node.
$nodeToRemove reffers to <item,
while $thedocument reffers to the root element node which is <publicidades>.
<item> is a child of <internas> not of <public...>.
EDIT:
Try adding:
$internas = $doc->documentElement->getElementsByTagName('internas');
right after:
$thedocument = $doc->documentElement;
and then:(EDIT2)
foreach ($internas as $node) {
$node->parentNode->removeChild($node);
}
