Re^2: What's wrong with this regex

Thanks for the quick answer guys.

Unfortunately four groups is not going to help, it should match anthing from 1.2 to 1.2.3.4.5.6 etc, or anything follows this structure.

To look for a substring matching [\d+\.]+ is also not an option, as there may be other matches in the string, like a simple number.

Sorry, I don't understand your answer. What exactly is wrong with the approach that uses split? `$_ = '1.2.3.4.5.6 foo bar'; if (/((?:\d+\.)+(\d+)/) { my @matches = (split(/\./, $1), $2) }` [download] Perl 6 - second systems done right	[reply] [d/l]

I'm thinking you don't need a beefy regex if that's all you want to do. How about something like this instead: `my $string = '12.34.56.78 asdfasdfasdfasdfasdf'; my $numbers = shift @{[split ' ', $string]}; my @numbers = split '\.', $numbers; use Data::Dumper; print Dumper(@numbers) if $numbers =~ /^[\d.]+$/;` [download] EDIT: Whoops, sorry moritz - I confess to only skimming your answer and didn't notice that you had already suggested using split. Apologies!	[reply] [d/l]
