> Take the following code:

>     (setq re "mailto")
>     (string-match re address)
>     (match-string 0 address)

These are 4 separate expressions.  How do you run them?
My crystal ball says that the problem is the code you unknowingly run
between each one of those expressions.  If you run them as a single
expression such as

    (let ((address "mailto:alexis@example.com")
          (re "mailto"))
      (if (string-match re address)
          (match-string 0 address)))

I'm pretty sure you'll get what you want.
