No need for initializers here.

No need to test for hr != S_OK and alter failure code after that I guess.

Use neutral CLSID_DOMDocument. Minor things - useless comment, and 
LPVOID* -> void**.

Same here, you don't need to initialize that. Please use shorter names, 
like 'root', 'document' or something.

hr != S_OK works.

P.S. it makes sense to test xml parsing part with native msxml first. 
This will hopefully show some problems with builtin msxml.
