First thing to do is to read about regexen. They are really important for most things you do with Perl. I'd recommend that you start with perlretut, perlrequick, perlre and perlreref.

When you have done that you will know that a negated character class like [^a-zA-Z\d.:] is what you are after. But read the documentation first.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
