I am not sure about xemacs but in emacs you do:

M-x whitespace-cleanup

I have the following in my .emacs:

;; Function to untabify a buffer
(defun untabify-buffer () (interactive)
  (whitespace-cleanup)
  (untabify (point-min) (point-max)))

(global-set-key [f7] 'untabify-buffer)

So pressing F7 eliminates all tabs and trailing spaces. I used to have
this done automatically when saving a file, but that was causing more
problems than it solved (usually code is not clean - if I have the
setting in my .emacs it doesn't mean that everyone does).
