How to extract raw link and description from the "link" element?

How to extract raw link and description from the "link" element?

[Marcin Borkowski]

Hi all,

so I have this:

[[file:whatever.org][Some link]]

How do I extract bith parts of this link programmatically?

My use case is that I have an Org tree of links, and I want to export
them to certain XML format.

TIA,

Probably there is some more elegant way but if you run this on a link,
you get the two pieces I think. In a filter or exporter, you might
replace (org-element-context) with the link element/object

#+BEGIN_SRC emacs-lisp
(defun parse-link ()
 (interactive)
 (message-box "%s"
 (cons
  ;; path
  (org-element-property :path (org-element-context))
  ;; description
  (buffer-substring
   (org-element-property :contents-begin (org-element-context))
   (org-element-property :contents-end (org-element-context))))))
#+END_SRC

Have you considered a custom exporter?  Just a little thought.

That's exactly what I'm writing.  It just hadn't occured to me to use
the parsed version in the element tree – I just concentrated on
exporting the headlines (which contain the links).  Stupid me.  Thanks
for this (obvious) tip!
