Re^2: How to remove roman numbers

Thank u mr. moritz for your reply. But Don't you think that if author name start with I , V , M ,etc then it will remove that letter from that name. and author name will be change.

As \w Match a "word" character , \d Match a decimal digit character, i want to know is there any special character for roman number also

As \w Match a "word" character , \d Match a decimal digit character, i want to know is there any special character for roman number also Even if it existed it would only help you if the roman numerals were written with special character, for example Ⅰ U+2160 ROMAN NUMERAL ONE instead of I U+0049 LATIN CAPITAL LETTER I Perl 6 - the future is here, just unevenly distributed	[reply]

As long as there's no word boundry touched, it won't remove the "I" in the author name; however, it will remove the personal pronoun "I". I'd do something like this: `#!/usr/bin/perl -l use strict; use warnings; my(@data) = q( 1. Iilliam H. Schneider, IV 2. William Vassilakis, II 3. Alessandro Calvi, I ); foreach my $data (@data) { $data =~ s/\b[IVXLCDM]+\b//g; chomp $data; print "$data\n"; }` [download] I used "Iilliam" instead of "William" for demonstration purposes.

Unfortunately, you are going to clobber middle initials as well :-( `knoppix@Microknoppix:~$ perl -E ' > $name = q{John I. Jones, IV}; > say $name; > $name =~ s{\b[IVXLCDM]+\b}{}g; > say $name;' John I. Jones, IV John . Jones, knoppix@Microknoppix:~$` [download] Perhaps doing something to remove the comma as well and making the assumption that you can anchor to the end of string? Cheers, JohnGG	[reply] [d/l]
