in reply to Easy way to capture STDOUT and STDERR without IPC

If you don't need the entire string and you'd rather loop you can do something like this: 
open my $CMD, '-|', 'ls 2>&1' or die $!;
while (<$CMD>) {
    print if /\.xml/;
}
close $CMD or die $! ? 'Pipe failed' : 'Program error: ' . ($? >> 8) ;
