In addition to the replies above, your actual error is because of the embedded / in: 
    m/http://www.[a-z]|[A-Z].[a-z]/i

There are several solutions, the simplest is to use some other character as your delimiter, for example: 
    m!http://www\.[a-z]+\.[a-z]+!i

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • 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.
  • Please read these before you post! —
