In the OP an example line starting with a four digit number is given. The OP gives a regex for capturing the number and the rest of the line separately but is asking how to skip lines containing 'group' at the same time. ikegami gave a good response.

That is exactly why I said that the requirement could not have been that simple. Another example of an "XY-problem"!

It is not that simple I suppose. But ikegami code works great. `my $Line = "1243 That will efficiently match a nonempty group with mat +ching parentheses two levels deep or less."; if ($Line =~ /^(?!.\bgroup\b)(\d{4}) ([^.]+?[.\!\?])$/){ print "$1\n$2\n"; #Does not print } elsif ($Line =~ /^(?!.\bgXroup\b)(\d{4}) ([^.]+?[.\!\?])$/){ print "$1\n$2\n"; #Prints }` [download] Though it solves my original query just wondering if it is possible to check the word in the second group of (). Thanks ramprasad27 for the "\." point. I didnt know that earlier. -Dominic	[reply] [d/l]
