Hello,

I, an Emacs Lisp newbie, want to get a list of all top-level headings of the current buffer. My approach so far is:

(defun test-org-map()
  (interactive)
  (setq headings '())
  (org-map-entries (lambda ()
                     (setq current-header-item (org-element-property :title (org-element-at-point))
                     (message "Header: %s" current-header-item)
                     (message "Is String: %s" (stringp (org-element-property :title (org-element-at-point))))
                     (setq headings (append current-header-item headings))
                     )
                   "LEVEL=1"
                   )
  (dolist (heading headings)
    (message "Header Item: %s" heading)
    )
  )

This gives the otput:

Header: AAA
Is String: t
Header: BBB
Is String: t
Header Item: 66 [3 times]
Header Item: 65 [3 times]

so basically the (org-element-property :title (org-element-at-point) does exactly what I want, but building the list does not what I want. I suppose that comes from a fundamental misunderstanding of how strings work in elisp.

I would appreciate a short explanation (or pointers) why this does not work. And of course, I am very open to completely different, likely better, approches to that simply problem!

Thanks,
Florian
