Read XHTML with XDocument?

Question

How to read XHTML with XDocument, without downloading DTD. How to resolve the DTD references? No, you can't just say:

settings.ProhibitDtd = false;
settings.XmlResolver = null;

as given in some previous answer, which is absolutely wrong. What about the entities then:   Also I am not interested in HTMLAgility pack, again wrong answer, as I have valid XHTML.

Answer 1

Found the solution, you have to manually cache all the DTD (see Mauricio Scheffer comment above), it looks like the best solution:
