I found three examples of org-next-item usage, two of which are shown here (the third one is a bit subtler): * org.el: --8<---------------cut here---------------start------------->8--- (defun org-skip-over-state-notes () "Skip past the list of State notes in an entry." (if (looking-at "\n[ \t]*- State") (forward-char 1)) (while (looking-at "[ \t]*- State") (condition-case nil (org-next-item) (error (org-end-of-item))))) --8<---------------cut here---------------end--------------->8--- * org-mouse.el: --8<---------------cut here---------------start------------->8--- (defun org-mouse-for-each-item (function) (save-excursion (ignore-errors (while t (org-previous-item))) (ignore-errors (while t (funcall function) (org-next-item))))) --8<---------------cut here---------------end--------------->8--- As you can see, the second almost matches what you came up with, but the condition is simpler: the code *uses* the error raised to get out of the (otherwise infinite) loop, so there is no need to check what org-next-item returns.
