And this is another."; @all_words = ($str =~ /\b(\w+)\b/g); print join( ', ', @all_words), "\n"; @some_words = ($str =~ /\s(\w+)\s/g); print join( ', ', @some_words), "\n"; Quite a big difference ain't it? \b matches 0 characters just between a word and non-word character, while \s matches one space.
