[2.0] [VS 2005] WebBrowser control issue

I have a WebBrowser control that loads a site. There is one page that does not display quite right so I would like to get the contents of that page just before it is rendered in the control so I can adjust one line and then display said page.
How would I go about doing something like this?

I've been able to create a Navigating event handler that recognizes the page it is about to go to. webBrowser1.DocumentText contains the HTML contents that is already displayed so I am not sure if that could be of any help.

Any suggestions would be muchly appreciated.

I don't see any replies to this thread so this might be non-trivial. I'll ask again just to be on the safe side though. Thanks to anyone who can provide guidance.
