Depending on what the OP meant, the following would both work:

- r"^(?!mystring)" (the string does not occur at the beginning)
- r"(?!^)mystring" (the string occurs elsewhere than the beginning)
  [Someone else's interpretation]

Both are "regular expressions" even in the academic sense, or else
have a translation as regular expressions in the academic sense.
They're also Python regexps. So I don't know what you mean.
