Regex exp again... need to match exactly two letters.

[Merlin]

($row[0] =~ /^[A-Z]{2}$/)

Shouldn't this match a line that has ONLY the country code on it, ie;

AU
US
Fred's AUSTRALIA
Bills US Postal Service. GA

and I only want it to return line 1 and 2. That is
AU
and
US

So it has to match a line that has ONLY two capital letters in it.

thanks

And that's exactly what the pattern '^[A-Z]{2}$' does. Why do you think
it doesn't?

yes. if it does not work you must examine what $row[0] contains
at the time of the match. maybe you are testing the wrong variable,
or maybe it contains extra stuff like spaces.

No, it should match a STRING that has ONLY the country code on it, plus an
optional trailing newline.

If your string has multiple lines in it, you'll need to add the /m
modifier.

Now, what are you doing, and what's not working like you'd expect?
