Is it possible to use C ++ to intersect the DOM with C # BHO?

Question

I am writing a helper browser object (BHO) for Internet Explorer in C #!

I want to search for text nodes in the DOM, which requires me to cross the entire DOM tree if I want to distinguish between text nodes and other types of nodes. This supposedly takes a lot of time in C #, but should be almost instantaneous in C ++ (?).

Is there a way to perform a move in C ++? A DLL that I can call from C #, possibly using DllImport? Is it easy to pass HTMLDocument to my external C ++ method?

Any other ideas?

Hooray!
