What in case when there will be 1.com in the test only? Is it valid url or not?
www in the url isn't mandatory.
I think you are not able create universal expression what will handle all of
your possible or broken URL.
Made it in 2 steps:
1. extract anything from your text what can looks like URL
2. check validity
