I'm guessing it could then be done more elispishly as

(setq dog (buffer-substring
   (re-search-backward "<h1\\|<h2\\|<h3\\|<h4\\|<h5" nil t)
   (re-search-forward "</h1>\\|</h2>\\|</h3>\\|</h4>\\|</h5>" nil t)))


How about if search fail?

Evaluating of

  (buffer-substring nil nil)

take (wrong-type-argument integer-or-marker-p nil).
