Lookahead/Lookbehind Regular Expression...by mogmismo (Novice) |

mogmismo has asked for the wisdom of the Perl Monks concerning the following question: So, I'm trying to match, in a string, all values that are abbreviations. In this string: "a history of u.s. coast guard aviation." I would like the "u.s." to become "us" but not replace any other periods. Another example would be taking "M.C. Esher" and converting to "MC Esher" So far, I can remove the middle dot, with a: $string =~ s/(?<=\w)\.(?=\w)//g;But I can't figure out how to do a lookahead/lookbehind/lookahead/lookbehind... I've tried this, and it fails: $string =~ s/(?<=\w)\.(?=\w)\.(?=\s)//g;Any ideas, Monks?
