How to convert HTML elements to windows controls!!!!!! (Any possibility?)

Question

I have about 100 XML files(with XSL that will convert each one of them to HTML )
I am planning to use a webbrowser control to fetch the "*.html" file.
At the same time i want the HTML elements in webbrowser to act based on some event.
which means if i press some button outside webbrowser, the HTML element say a textbox should have its TEXT value changed to something else.
Its very important for me to handle HTML elements event based on its properties and value.
Please offer some ideas or solutions if anyone knows. (cas i dont find a hint anywhere else)
THANKS A BUNCH!
