The last line was throwing Not Found exceptions for me until I switched out ownerDocument for parentNode – I’m guessing this could depend on whether the node you’re replacing is top level or not.

So, line 10: $oldNode->parentNode->replaceChild($newNode, $oldNode);

Now if only PHP would actually roll out some core extensions that fully implemented the things they said they were implementing. Getting pretty sick of it these days.

Cheers,
