[O] org-element - canonical way to parse only headline at point?

[Thorsten Jolitz]

Hi List,

with the new parser, how do I parse only the headline at point?  There
are ARGS in the parser/mapper functions that restrict parsing, but I
suspect that still the whole buffer is parsed for the genealogy - right?

With my current knowledge I would either narrow the buffer to the subtree at
point or copy this subtree to a temp-buffer before parsing/mapping it,
but maybe there is a better way?

Would this be a valid template (a simple and fast solution)?

#+begin_src emacs-lisp
  (save-restriction
   (org-narrow-to-subtree
    (org-element-map (org-element-parse-buffer 'headline t) 'headline
      (lambda () ...)
      nil t t)))
#+end_src
