You don't want to split the file using s/\n/ms, that's a substitution operator. Use /\n/, a match operator.

    Sorry, meant:

    split /\n/sm

    Ideas??

      The following code should work fine, assuming $data contains what you're trying to split:
      #!/usr/bin/perl -w use strict; my $data = q|Title Line Author Line URL Line |; my @data = split /\s*\n\s*/, $data; my $i; for ($i=0; $i<=$#data; $i++){ print "$i: $data[$i]\n"; }
      However, if you're reading from a file, i suspect you want something more like this:
      #!/usr/bin/perl -w use strict; open DATA, 'splitdata.txt'; my @data; while (<DATA>) { chomp; s|^\s+||; s|\s+$||; push @data, $_; } my $i; for ($i=0; $i<=$#data; $i++){ print "$i: $data[$i]\n"; }
