VS 2008 Webbrowser.Sourcecode reading + gathering text(+finding)(code) + dropping in txtbox

So, all of you..
Hello..

I'm working on a small project, and really FAIL so hard at this, I've googled for almost half of an hour, with no luck.
I let my webbrowser1 navigate to a page after the user clicks on the button.
So, my thing: On that page, there's something in the source what the USER needs. ([s]he can do CTRL+U CTRL+F but that's not humanfriendly at all!)

This is the part of that page I need dropped in a textbox:
(The part I need is blue because it's a link and it's underlined, that part is what I need from the source code)
<a href="/url?q=http://www.whattheUSERwrote.com/..">http://www.whatthEUSERWROTE.com/..</a>

(This is a part from the page, and I just need that underlined dropped in a textbox, or even copied to clipboard (Clipboard.SetText)
I know this sounds impossible but anyone please?;x ;((
IDEA/HELP/HINT: YOU COULD GET IT MAYBE WITH LETTING IT COPY EVERYTHING BETWEEN THE QUOTES BEHIND url?q= because there's only one url?q= in the whole source-code.

I hope you all understand me, and can help me:(
Thanks in advance!x
