I would like to get the complete HTML for the currently loaded page,
from an external application. Is there any way to do this? If not, is
there a way I can read the values from hidden text fields?
Specifically, I'm trying to read values from HTML elements that look
like this:

<input type="hidden" id="test" value="56456456" />

Through the normal IAccessible interface I can't read the values of
hidden fields. I was hoping that ISimpleDOMNode would be able to do
this. Am I on the right track? Thanks!
