Re: Regexing a block of text in between patterns

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;` [download] Otherwise you will leave some junk at the beginning of each block.

Hello CountZero 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 mwa	[reply]

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! CountZero A program should be light and agile, its subroutines connected like a string of pearls.
