Re: Capturing the nth word in a string

Perhaps since you're only interested in one 'word' you could save Perl the bother of capturing all of them:

  print ( $str =~ /(?:\w+\W+){3}(\w+)/ ), "\n";

Of course having n (3 in this case) buried inside the regex doesn't exactly make for a general solution.

You don't have to hard code the '3' here. It can easily be a variable. This is a good solution.	[reply]

Yes! Indeed this is an excellent solution. Thanks for the efford, I will write it down somewhere for future reference. :-) `my ($nth) = $str =~ /(?:\w+\W+){3}(\w+)/; # capture 4th word` [download]	[reply] [d/l]
