Detect DOM modification in Internet Explorer

I am writing a Browser Helper Object for ie7, and I need to detect DOM modification (i.e. via AJAX). So far I couldn't find any feasible solution.

From stackoverflow mojo

• The best thing I could recommend is the Internet Explorer Developer Toolbar which allow you to view changes in the DOM.

  From GateKiller

• You want to use IMarkupContainer2::CreateChangeLog.
