    </internas>
    <externas>

    </externas>
</publicidades>

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);
}
