Hi,
Alle Leerzeichen entfernen: $string =~ s/\s//g; (edit: drittes / nachgeholt) Kleinbuchstaben: $string = lc($string); Umlaute musst Du ggf. gesondert berücksichtigen, je nach locale. edit: Kleinbuchstaben mittels RegEx: $string =~ s/(.*)/\L$1/; Last edited: 2012-12-03 11:17:36 +0100 (CET) Everyone knows that debugging is twice as hard as writing a program in the first place. So if you're as clever as you can be when you write it, how will you ever debug it? -- Brian Kernighan: "The Elements of Programming Style"
