Re: Function for retrieving the link of an Org Mode buffer

[John Kitchin]

I would probably do it like this:

(org-element-map (org-element-parse-buffer) 'link
  (lambda (lnk)
    (let ((lnkplist '()))
      (setq lnkplist (plist-put lnkplist :link (org-element-property :raw-link lnk)))
      (when (org-element-property :contents-begin lnk)
(setq lnkplist (plist-put lnkplist :desc (buffer-substring-no-properties
 (org-element-property :contents-begin lnk)
 (org-element-property :contents-end lnk)))))
      lnkplist)))

        links))))
#+END_SRC

I would really appreciate any feedback.
