So given your new data, I am unsure what data would be placed in the hash.
From your example, what is expected?
Wags ;)

Many thanks to "Wagner-David" for the code. I've slightly changed it, as
below, but have still further questions.
use strict;
my $counter = 1;
my %Headinghash;
my %Texthash;
while (<DATA>) {
chomp;
if ( /^(\d+)\.\s+(.*)/ ) {
$counter = $1;
$Headinghash{$counter} = $2;
}elsif ( ! /${counter}\./ ) {
$Texthash{$counter} .= $_;
}else {
$counter = '';
}
}
foreach my $MyKey (sort {$a <=> $b} keys %Headinghash) {
print "HEADING: $MyKey, $Headinghash{$MyKey}\n TEXT: $MyKey,
$Texthash{$MyKey}\n";
}
__DATA__
1. This is a heading
........text in between ...
1.1. A subheading
... and this is text after subheading 1.1
1.2. Another subheading
2. Another heading
.......
3. Yet another heading
......
--- end code -----------------------------------------
This works fine for DATA as it is, but unfortunately my requirements are
more specific.
I would also like to use it for such data as:
__DATA__
1. This is a heading
........text in between ...
1. List item 1
2. List item 2
..... more text in between
1.1. A subheading
... and this is text after subheading 1.1
1.2. Another subheading
2. Another heading
.......
3. Yet another heading
......
---------- end data -----------------------
So checking on an initial digit is not specific enough, because in between
a heading "$counter" and the next subheading "$counter.1", there might be a
line beginning with "$counter" = a list entry. I really need to do a loop
moving up a counter, *and* I need the search to be "position-aware".
I guess my question boils down to: How to code "when there's a match of
"1\.\s" in the beginning of a line, check whether there's a "1\.1\.\s"
after the end of that line - if so, assign everything in between the end of
that line and "1\.1\.\s." as a hash value, and move up the counter to 2; if
not, move up the counter to 2 and search for a line beginning with "2\.\s"
*after* "1\.1\.\s". "
