Aloha all,
Inspired by John Kitchin's org-ref, I'm working on a little function that
returns all the pieces of an Org mode file that are candidates for cross
referencing. The helm package lets me choose from among the candidates
and then another little function inserts the chosen link.
This all works for me, and I'm finding it really useful. The only
slight problem is that I haven't been able to figure out how to
eliminate all the headings that won't be exported. You'll see in the
code below that my simple-minded approach gets all the headings tagged
:noexport:, but it doesn't understand that the tag is inherited by
descendants. Is there a practical way to identify descendants for my use
case?
(defun tsd-get-names-labels-and-headings ()
(interactive)
(save-excursion
(goto-char (point-min))
(let ((matches))
(while
(re-search-forward "\\#\\+\\(name\\|label\\):\\s-\\(.*\\)" (point-max) t)
(add-to-list 'matches (match-string-no-properties 2) t))
(dolist (heading (org-map-entries 'org-heading-components))
(when (and (nth 4 heading) (not (search "noexport"(nth 5 heading))))
(add-to-list 'matches (nth 4 heading))))
(dolist (properties (org-map-entries 'org-entry-properties))
(when (cdr (assoc "CUSTOM_ID" properties))
(add-to-list 'matches
(format "#%s" (cdr (assoc "CUSTOM_ID" properties))))))
(sort matches 'string<))))
All the best,
Tom

Yes, use the MATCH argument to org-map-entries.
Many thanks to Jonathan Leech-Pepin for pointing this out to me off
list.
All the best,

For the matching portion itself the following should work:
(org-map-entries (lambda () (org-element-property :raw-value
(org-element-at-point))) (format "-%s" (mapconcat 'identity
org-export-exclude-tags "-")))
Rather than try and search for the tag afterwards, create a string that
will match all non-exporting tags and have them excluded from the match
itself (by default this will be "-noexport" but if you add "test" it will
become "-noexport-test"). It also gives you the exact raw value of the
element. Using just 'org-element-at-point would give you the entire
element, allowing you to display the :raw-value in your output but also
have the associated :begin to jump to, removing the need to search for the
headline again later on.
