in reply to How to capture all occurances from a slurped file.

You were very close to solving the problem. You just need to repeat the search multiple times, as perl will continue the search when the last one ended.
use strict; use warnings; use Data::Dumper; my $data; # Modifying $/ in a limited context to avoid # affecting other areas of the code. { local $/; $data = <DATA>; } # # Create the regular expression using qr{}x as it makes # the pattern much easier to follow (and maintain) # my $pattern = qr{ (\d+-) (\d+-) (\d+) (\s*/\s*) (\d+) (\s*/\s*) (\d+) }x; my @list; while ($data =~ /$pattern/g) { push @list,[$1,$2,$3,$4,$5,$6,$7]; } print Dumper \@list; __DATA__ PART NAME QUANTITY SECTION/FIGURE/ITEM Widget1 1 72-33-00/ 23/ 85 Widget1 1 75-20-00/ 11/ 10 Widget2 1 72-33-00/20/10 Widget2 1 72-33-00/20/70 Widget2 1 72-00-33/2/1 Widget2 1 72-00-33/2/20 Widget2 1 73-12-00/4/1 Widget2 1 73-12-00/4/220 Widget2 1 73-12-00/3/10 Widget2 2 79-20-00/9/1 Widget2 1 79-20-00/5/1
Note that I defined the regex before the loop. This makes the logic easier to follow, particularly when you use the 'x' modifier.
