I'm working on a cook book in .txt format and I'd like to tag in xml the title,the ingredients and the procedure of each recipe.

The text look like this:

1.TITLE OF FIRST RECIPE

abstract

Ingredient 1.
Ingredient 2.
Ingredient n...

Procedure...


2.TITLE OF SECOND RECIPE
...

1-I've tried to put all the file in one string and then apply the regex to it,but if the words matches,then I got printed all the text,and not just my line.

2-If instead I try to read the file line by line I can't search something like /[0-9]\. .*\n\n/ because I can't catch more than one \n.

3-Then I tried to create an array in this way 

my @array=split (//,$linea);

but then I don't know how to handle it(I'm a perl beginner and this is my first post).

Here is my last attempt.All the \n are doubled so I've changed them with a single \n.

#!/usr/bin/perl
use warnings;
use diagnostics;
use strict;

my $text_file="cookbook.txt";
my $output="output.txt";

open(my $INPUT,"<",$text_file ) || die "Error: $!\n";
open(my $OUT,">",$output) || die "Error: $!\n";

my $linea = do { local $/; <$INPUT> };

$linea=~ s/[\r\n]/\n/g;
$linea=~ s/\n\n/\n/g;
    
if ($linea=~ //) {
    print $OUT $linea;
}
close $OUT;
close $INPUT;
exit;

So,I just want to catch(and print just what I've matched!) some text between more than one \n.

Thanks in advance,and sorry for my english.
