in reply to Convert string to data structure

Here's another option:

use Modern::Perl; use Data::Dumper; my @array; my $str = "1. ...... AB_CD 1.1 ...... EF_GH 1.2 .... IJ_KL_MN 2. ............ +OPQR"; while ( $str =~ /(\d+\.\d*)\s+\.+\s+(\S+)\s*/g ) { push @array, { chapter => $1, name => $2 }; } say Dumper \@array;

Output:

$VAR1 = [ { 'name' => 'AB_CD', 'chapter' => '1.' }, { 'name' => 'EF_GH', 'chapter' => '1.1' }, { 'name' => 'IJ_KL_MN', 'chapter' => '1.2' }, { 'name' => 'OPQR', 'chapter' => '2.' } ];

The regex:

/(\d+\.\d*)\s+\.+\s+(\S+)\s*/g ^ ^ ^ ^ ^ ^ ^ ^ ^ | | | | | | | | | | | | | | | | | + - Globally | | | | | | | + - 0+ spaces | | | | | | + - Capture non-whitespace characters | | | | | + - 1+ spaces | | | | + - Multiple periods | | | + - 1+ spaces | | + - Capture zero or more digits | + - Capture a period + - Capture one or more digits

Hope this helps!

    Thank you very much. All your answers are so great. And it was interesting to try all. A lot of great techniques. I could learn a lot of new skills and got ideas how to solve such a problem.

    Especially this solution "matching operator in global mode" I like because it is very easy to understand.
