roboticus, I decided to give the name transform a try, and so far it looks pretty good.

#!/usr/bin/perl use strict; use warnings; my @roman_numerals = qw(I II III IV V VI VII VIII IX X); my $roman_numerals_string = join('|',@roman_numerals); sub name_transform { my $name = shift; # If a suffix is so long it needs a comman, let's get it here. my ($base_name,$pre_suffix) = split(', ',$name); # Split the rest of the name by the spaces. my @name = split(' ',$base_name); # Now check the first array item to see if it is a common prefix. # Some are there for fun. my $prefix = $name[0] =~ /(?:Lady|Lord|[MD][rs]|Mrs|Miss|Pres|Gov|Se +n|officer)(?:|\.)/ ? shift @name : ''; # Now check the last item of the array to see if it matches some com +mon suffixes. # More Roman numerals can be aded. my $suffix = $pre_suffix ? $pre_suffix : $name[-1] =~ /(?:Jr|Sr|Esq| +$roman_numerals_string)(?:|\.)/ ? pop @name : ''; # All which should be left is the bare name. Even if only the first +name is left, # it will be treated as the last name and maybe sorted accordingly. my $last_name = pop @name; my $first_name = shift @name // ''; # Every name left should be middle names. my $middle_name = @name ? join(' ',@name) : ''; return [$last_name,$first_name,$middle_name,$prefix,$suffix]; } local $\ = "\n"; my @names = ('President Barack Hussein Obama II','Mrs. Amanda King','D +r. Feelsgood', 'Miss America','Officer Andy','Henry VIII', "Dr. John Smi +th", "Eucalyptus A. Tree, Esquire","Roboticus", "Lady Aleena, +Baker of cookies", 'Aleena Zarahlinda ibn Robert al-Hajnal Chaoshi-Mnemosyni +od I'); for my $person (@names) { my $names = name_transform($person); print join('|',@{$names}); }

returns

Obama|Barack|Hussein|President|II King|Amanda||Mrs.| Feelsgood|||Dr.| America|||Miss| Andy|Officer||| Henry||||VIII Smith|John||Dr.| Tree|Eucalyptus|A.||Esquire Roboticus|||| Aleena|||Lady|Baker of cookies Chaoshi-Mnemosyniod|Aleena|Zarahlinda ibn Robert al-Hajnal||I

What do you think?

Have a cookie and a very nice day!
