Re^2: substitute instead global matching for nested matches

This returns the first element in the 2nd match. I need to get the last element. So the result must be

#4
r2 !
#5
r5 !

And your code is restricted to 3 consecutive elements separated by lines. I need to a more generic solution because my lists are changing variably. Sorry did not mention that clearly in my previous post (the global match ((\S+\s+\S+\s+)*) implies that). So a $fc could be

#4
r1 !
#5 
r3 !
r7 !
r10 !
#8
r0 ! 
r1 !

I need to get the last r member. Any help appreciated.

The following meets your current spec as I understand it: `use strict; use warnings; my $fc = <<FC; #4 r2 ! #5 r3 ! r7 ! r10 ! #8 r0 ! r1 ! FC print "$1\n$2\n" while $fc =~ /^(#\d+)[^#]*^([^#\n]+)$/gm;` [download] Prints: `#4 r2 ! #5 r10 ! #8 r1 !` [download] True laziness is hard work	[reply] [d/l] [select]

It works! GrandFather, thanks for the tip about pattern matching!	[reply]
