Re: Perl Module for identifying country name

[talexb]

It's a little difficult to comprehend what you're asking for, but my guess is that you could achieve your goal by using grep on the file for the country name that you're looking for. Does that help?

Actually what I want is just to find which country names are there in a text file

for grep i think i will need to mention if it is United States or Germany right? This way I can miss the country name Canada if it is in the file

You can use a regular expression to find all (English) country names.

BTW, you will not find "United States" with this regex since the official name is "United States of America".
