in reply to Split and empty strings

Are the empty lines at the end, perhaps? By default, split trims the returned list at the first empty value. See perlfunc:split for the exact terms.

Update: I just tried this code, and it works as I expect. 

$_ = "one
two
three

four


";
foreach my $line (split(/\n/)) {
    print "$line\n";
}

The output for my Perl 5.6.1 system is:

$ perl ~/split.pl
one
two
three

four
with the blank printed between three and four, and nothing thereafter.

    No, they're scattered randomly through the string. But thanks for the idea, TheoPetersen. I've looked at perlfunc:split again - still no joy.

    Slight modification - I've realised I don't need the /m on the regexp. Works the same without.

    andy.

    update: thanks again. I've realised that I was being stupid - the onset of tunnel vision. split was doing exaclty what it ought, as your example shows, but the regexp was returning extra blank lines.
