But I get the notice:

I want the extension to be valid for all DOM nodes that are derived from
DOMNode, such as DOMElement, DOMAttr, DOMNodeList, DOMText, etc...
I try not to extend all the classes one by one.
Due to the internals of the DOM extension, you need to register the
class types that are actually instantiated and not the underlying base
DOMNode class. Unfortunately in your case this means you need to
register all of those classes separately.
$dom->registerNodeClass('DOMElement','MyDOMNode');
$dom->registerNodeClass('DOMAttr','MyDOMNode');
$dom->registerNodeClass('DOMText','MyDOMNode');
