I found the very useful but sadly outdated snippet from 2011. If anyone
is interested, the following snippet implements the same functionality
within the new export framework.
--8<---------------cut here---------------start------------->8---
(defun org-export-remove-prelim-headlines (tree backend info)
"Remove headlines tagged \"prelim\" while retaining their
contents before any export processing."
(org-element-map tree org-element-all-elements
(lambda (object)
(when (and (equal 'headline (org-element-type object))
(member "prelim" (org-element-property :tags object)))
(mapc (lambda (el)
(let ((new-object
(if (equal 'headline (org-element-type el))
(org-element-put-property el
:level (1- (org-element-property :level el)))
el)))
(message "%s level %s"
(org-element-property :raw-value new-object)
(org-element-property :level new-object))
(org-element-insert-before new-object object)))
(cddr object))
(org-element-extract-element object)))
info nil org-element-all-elements)
tree)
(add-hook 'org-export-filter-parse-tree-functions
'org-export-remove-prelim-headlines)
--8<---------------cut here---------------end--------------->8---
In addition it promotes all headlines under the removed "prelim"-tagged
headline. This is useful to support structures like the following.
--8<---------------cut here---------------start------------->8---
* Appendix :prelim:
#+LaTeX: \begin{appendices}
** Definitions
** Data Sets
** Tooling
#+LaTeX: \end{appendices}
--8<---------------cut here---------------end--------------->8---
Best,
