I have these strings:

I've been trying to use awk for a while, but since I'm not familiar with it, I'm still struggling. But, I'm also open to other suggestions.
I just want to look for the keyword INVALID: EXPIRED and then return the domain name at the next line, and finally, it should have this output:
www.domain2 domain6.com domain7.com
