Can someone help me build a regex that parses this txt file for only the top level domains that have more then 2 characters and does not have special characters in it

http://data.iana.org/TLD/tlds-alpha-by-domain.txt

I say no special chaters due to the lines like this XN--0ZWM56D

Depending on the regex engine, programming language and the hardware platform you are using, then either

^[a-z]{3,}$

or

^[a-z]{3,}\r$

with the 'multiline' and 'ignore case' options set should do the trick.

If not, then please read the posting guidelines and provide us with the additional information and what is not working.

I will be testing this out later today.

Sorry I did not give the additional info
