Hi List,
when I change the signature of my new function `tj/rewire-element' by
adding an mandatory 'element' argument, it can be used in
`org-element-map' calls too:
#+begin_src emacs-lisp
(defun* tj/rewire-element (element &optional replace &rest args &key type &allow-other-keys)
"..."
(let* ((elem (or element (org-element-at-point))) ...)))
#+end_src
e.g. for converting all src-blocks in a buffer to example blocks:
#+begin_src emacs-lisp
(org-element-map ptree 'src-block
(lambda (--elem)
(tj/rewire-element --elem nil
:type 'example-block
:header nil)))
#+end_src
but the above just returns a list of strings with the created
example-blocks because argument 'replace' is nil:
,----
| (tj/rewire-element --elem nil ...)
`----
When I set that argument to non-nil (t or 'append or 'prepend), things
stop working because replacing/appending changes the parsed buffer,
but the :begin and :end properties of the already parsed elements are
not adjusted and I use them e.g. to delete a region.
Without using the export-framework (which seems overkill in this
case), is there a way to make this work anyway?

cheers,

You can make replacements backwards, i.e., starting from the bottom of
the buffer.

Its not really obvious for me how to do that. You mean simply by doing
it in 2 steps
1. map parse-tree and get the result list
2. goto point-max of buffer and use the result list to replace mapped
elements backwards
or rather a 'trick' to make org-element-map process the parse-tree
backwards and thus start with replacing the last element?
Not sure what this trick would be - partly reverse the parse-tree?

Yes, that is what I mean. Just make sure to reverse the list returned by
`org-element-map'.
