in thread How we can do regex of this?

Somewhat simpler:
use strict; use warnings; my @names = split(' ', <DATA>); my @lenghts = split(' ', <DATA>); my %sizes; @sizes{@names} = map { length } @lenghts; sub strip_space { my ($str) = @_; $str =~ s/^\s+//; unpack 'A*', $str; } my %data; while (defined(my $line = <DATA>)) { my $pos = 0; foreach my $name (@names) { push @{$data{$name}}, strip_space(substr($line, $pos, $sizes{$name})); $pos += $sizes{$name} + 1; } } use Data::Dumper; print Dumper \%data; __END__ Mod Sub-Module Model Serial ---- --------------------------- ------------------ ----------- 1 Distributed Forwarding Card WS-F6700-DFC3CXL SAL1434RLPY 3 7600 ES+ DFC XL 7600-ES+3CXL JAE14520N29 3 7600 ES+T 20x1GE SFP 76-ES+T-20GQ JAE145301XM 5 Policy Feature Card 3 7600-PFC3CXL JAE14330E6J 5 C7600 MSFC4 Daughterboard 7600-MSFC4 JAE14320QBE 6 Policy Feature Card 3 7600-PFC3CXL JAE14330EAO 6 C7600 MSFC4 Daughterboard 7600-MSFC4 JAE14320QA8 7 Distributed Forwarding Card WS-F6700-DFC3CXL SAL1433QHBR 8 Distributed Forwarding Card WS-F6700-DFC3CXL SAL1433QXF9

[ambrus]: Corion: I think I parsed a HTTP header from a string with LWP once. You can definitely use that to create a HTTP message too. The problme is
[ambrus]: that if you do that, you'd have to find where each HTTP response ends, which is nontrivial if you want persistent connections (essential for performance if you have small requests).
[Corion]: ambrus: Yes, ideally an API that I feed the incoming data piece by piece and that I can ask "is that response done" and "what should I do next" and "please construct the appropriate redirect for me"
[Corion]: ambrus: Yes, ideally the module would do all that nasty stuff for me and give me a way to ask it what the current situation is
[ambrus]: Corion: you could also consider using some wrapper over the multi interface of curl, I think Net::Curl might be a good one, since implementing enough of what it expects from the event loop might be easier than a full AnyEvent interface.
[ambrus]: Corion: you could also consider using IO::Async and its POE driver and some HTTP module for it, but I don't know if that would solve your problems with AnyEvent+POE
[ambrus]: Corion: wait, you didn't say POE. You said Prima, let me look up what that is.
[ambrus]: Corion: have you considered just writing an AnyEvent integration for that thing?
[ambrus]: Or perhaps pushing schmorp to write one?
[ambrus]: Also, searching for an existing one on CPAN obviously
