I'm shocked that no-one mentioned the really obvious solution - don't use a regex! 
my $i = 0;
while (my ($args1, $args2) = split('.', $_myfile[$i++]))
{
    print "$args2\n";
}

If you're parsing, a regex should be your last resort. You should have at least considered the following options first:
  1. Judicious use of split. (In the case above, we would've needed another split.) Use this if you have delimiters (like a period?)
  2. Judicious use of unpack. Use this if your data is column-formatted. (Most work with mainframes or network protocols will use unpack, for example.)
  3. Now, and only now, should regexes be used. Regexes should be used if the above do not apply. They are harder to maintain and, if you don't know what you're doing, can be the cause of subtle bugs.

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.
