Firstly, do tell me if I am breaking the nettiquete.
I found someone asking online how to ignore a headline when exporting
to LaTeX. This e-mail is to avoid creating an account on that forum
and to provide a solution.
(require 'ox-extra)
(defun org-export-ignore-headlines-latex (data backend info)
"Hack of `org-export-ignore-headlines' for LaTeX: add a
conditional for the latex backend and replace 'ignore' with 'ignoreltx'"
(when (org-export-derived-backend-p backend 'latex)
(org-element-map data 'headline
(lambda (object)
(when (member "ignoreltx" (org-element-property :tags object))
(let ((level-top (org-element-property :level object))
level-diff)
(mapc (lambda (el)
;; recursively promote all nested headlines
(org-element-map el 'headline
(lambda (el)
(when (equal 'headline (org-element-type el))
(unless level-diff
(setq level-diff (-
(org-element-property :level el)
level-top)))
(org-element-put-property
el
:level (- (org-element-property :level el)
level-diff)))))
;; insert back into parse tree
(org-element-insert-before el object))
(org-element-contents object)))
(org-element-extract-element object)))
info nil)
data))
(push '(ignore-latex-headlines
org-export-ignore-headlines-latex
org-export-filter-parse-tree-functions)
ox-extras)
(ox-extras-activate '(latex-header-blocks ignore-headlines
ignore-latex-headlines))

This is on topic and can be useful for others without knowing the
context of the mentioned discussion. So, there should be no issue with
posting this here, especially if you provide sufficient context.

Note that this modified version of the function is derived from
org-export-ignore-headlines from ox-extra.el [1]
However, a part of the original function code is omitted.
AFAIU, this version also discards the headline contents, in addition to
the headline itself (unlike what org-export-ignore-headlines does).
Note that discarding headline + contents is also supported using
:NOEXPORT: tag.

Thank you for the link.

Sorry, I just had the version from 2014! :P As mentioned in the comment
of the new function, I just added a conditional and replaced "ignore"
with "ignoreltx". As a suggestion, it could be possible to replace
"ignore" with a variable and use another variable such that the headline
is omitted when other export types (latex, html, etc.) are used.
In any case: Thanks for almost 20 years!

It looks like almost verbatim copy of
https://orgmode.org/worg/org-faq.html#org11adb66 FAQ: 18.1. How do I
ignore a headline?
