Such simultaneous replacement could be implemented the same way as in mm-uu-configure that creates a composite regexp from all regexps: (defun mm-uu-configure (&optional symbol value) (setq mm-uu-beginning-regexp (mapconcat #'mm-uu-beginning-regexp (delq nil (mapcar (lambda (entry) (if (mm-uu-configure-p (mm-uu-type entry) 'disabled) nil entry)) mm-uu-type-alist)) "\\|"))) Then it's used like this: (while (re-search-forward mm-uu-beginning-regexp nil t) In case of replacements, it should replace the found composite regexp with the corresponding string from replacement pairs.
