in reply to Regexing a block of text in between patterns

You could split on 'Sidenote':

... my $filename = 'C:\letters.txt'; open my $fh, '<', $filename or die "Can't read $filename, $!"; my $text = do { local $/; <$fh> }; close $fh; my @sidenotes = split /(?=\[Sidenote:)/, $text; my $div_output = join "\n", map "<div>$_</div>", @sidenotes; print $div_output; ...

    Or rather
    my @sidenotes = split /\[Sidenote:.*?\]/, $text;
    Otherwise you will leave some junk at the beginning of each block.

      I purposely included the [Sidenote] text after understanding the OP's specification this way.

      Maybe I didn't read closely enough ...

      Thanks & Regards

        Now that you say it I looked again at his regex and indeed one could think that "[Sidenote:" is the breakpoint, which does not fully tally with his question.

        Well, he now has both options to choose from!
