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

cheers,
Thorsten

What about (org-element-at-point) ?

Thats why I asked - exactly the function I was looking for. Thanks.
