Hi List, I wonder how I can find out in a (elisp) program the points in the parse tree (returned by org-element-parse-buffer) where shared structures are used.
In the read-syntax, its easy to see (especially with `print-circle' set to non-nil): #+begin_src emacs-lisp #2=(org-data nil #1=(headline (:raw-value "header 1" [...] :parent #2#) [...] #+end_src but when processing the parse tree as a list in elisp, how can I detect the fact that ,------------ | :parent #2# `------------ refers to ,----------------- | #2=(org-data nil `----------------- i.e. points back to an already existing structure? -- cheers, Thorsten
