Return Top-Level Heading

Return Top-Level Heading

[Zach Sheffler]

[-- Attachment #1: Type: text/plain, Size: 270 bytes --]

Hello,

Is there a way to reference the top-level heading that a lower-level
heading belongs to? For instance:

* One
** Two
*** Three

If I have "Three", how can I get it to tell me that the top-level is "One"?
For reference, this is for an org-agenda-prefix.

Thanks!

Perhaps this:

(defun findTop()
    (interactive)
    (let* ((tree (org-element-parse-buffer))
           (curs_pos (point))
           (up_tree (org-element-map tree 'headline
                      (lambda (hl)
                        (and (> curs_pos (org-element-property :begin hl))
                             (= (org-element-property :level hl) 1)
                             (org-element-property :raw-value hl) ))))
           (local_up_tree (last up_tree)))
      local_up_tree))
