That's correct. A DOM tree is not a system identifier (effectively, a URI).
My question is if exist a way of validate a xml dom tree object, not a xml file.
Not currently as far as I know. For reasons of tradition, validation is typically done at parse-time.
There is no standard way in the W3C DOM interface to retain the information from <!ELEMENT ...> and <!ATTLIST ...> declarations in the DTD, so most Python implementations do not keep this information, which is needed to do validation.
(My own imp pxdom does keep the information, in a non-standard extended interface. So it would be possible to create a DOM-based validator based on this... it's something I'm considering doing myself, but not a priority at the moment.)
