This page answers your question exactly:

• Elisp Lesson: Repeated Find Replace

if you prefer emacs to ask you for each case, perhaps just to be sure your regex didn't find a bad match, see:

(defun wrap-markup ()
"Insert a markup <b></b> around a region."
(goto-char (region-end)) (insert "</b>")
(goto-char (region-beginning)) (insert "<b>")

the above is from a collection of simple elisp examples at
