in thread Store and match

I am not clear with your inputs because in your previous node you gave [Note] in same line and now in two lines. Any how the below code will work for your above input. It will also match note_values if more than one present in a single line.

use strict; use warnings; my $prev = 0; my $total = 0; while(my $x = <DATA>){ $prev = 1 if ($x =~ /^\[Note\]$/); my $count = 0; if (($x =~ /note_values/) && $prev){ $count = $x =~ s/(note_values)/$1/g; #if more than one note_va +lues present in a line $prev = 0; } $total = $total + $count; } print "Number of occurence: $total";
