how do I negate a sed match

I have a text file that has links in it.

I can write a match for sed to replace the link with anything.

For example:

Code:

http://www.google.com 
becomes
XxX

But what I'm after is not to replace the link with something but to remove everything else and just leave the link. I want a negative match. So that everything that matches is left alone but all non-matching text is removed.

Any ideas?
