Pattern Searching Grep

Question

i know there are alot of answers out there - but I am yet to find one which answers my question:

Hopefully someone can help!

I have a configuration file which is laid out like so:

define name{ name Stephen URL: www.stephen.com } define name { name Bob URL: }

What I need to do using grep is to search this file - and if URL is blank then return the name - in the above instance, it would return Bob.

Thanks in advance.
