Dyamic html to WebBrowser control

How do I dynamically write html to Microsoft's WebBrowser control? I Have a project which uses this control which I must add a feature. This feature will parse a text file for a user-supplied keyword (a search word). This perl-generated text file contains an indexing scheme for 120+ html pages consisting of:
Keyword | Html page name | Html page title | Sring w/keyword | keyword instance
As the file is parsed, if the keyword matches the search criteria, I need to spit out Html directly to the WebBrowser which would contain:
Page title | String containing keyword
with the keyword being a hyperlink to the page name.
I would like to do this without writing a temporary page to the user's hard drive.
Help!

If you find out, I'd be interested to know...
