Hahah, I can't be right all the time :D I didn't mean to use TLD, I
meant to use domain name, but not including sub-domained names :) I
don't even know what that is rightly called to exclude sub-domains.
Anyways, those, by virtue of your above description can have two or more
parts and there's not a simple way to extract that part without also
extracting the sub-domain portions.

Cheers,
Rob.

True. Not without some static rules and logic, including
knowledge of which ccTLDs have required or potential country-wide
SLDs. Though I think the solutions provided by yourself, Shawn, and
myself would suffice for most situations. I'm hoping Tedd will share
his as well.

Daniel:

I'm embarrassed to show it -- it's not as slick and condensed as
your's and Rob's

http://www.webbytedd.com/b3/parse-domain-collective/

Please be kind.

However, my code was to do something specific in my mind, namely to
pull out the domains that have specific TLD the user wants, reduce
the domains to their basic form (no sub domains), strip-out any
possible gremlins from the input text, and return no duplicates. I am
NOT saying that yours did anything different -- I'm just saying that
was *my* intent.

Cheers,

tedd

PS: I'm back from a long stretch of seminars on "Asset Protection". I
guess that my asset needs protecting. In any event, I now know more
about the relationships between Corporation, LLC, LP, Trust, and
other such fun matters than anyone should know.
