The global idea is correct, but I find that the implementation is too
low level. It also taints original e-latex back-end.
I suggest the following instead:
#+begin_src emacs-lisp
(defun ignore-empty-section (headline contents info)
(when (org-string-nw-p contents)
(org-export-with-backend 'e-latex headline contents info)))
(org-export-define-derived-backend my-draft-latex e-latex
:translate-alist ((headline . ignore-empty-section))
;; Optionally add a sub-menu entry in the latex menu.
:menu-entry (?l 99 ((?d "As a draft PDF file" my-draft-latex))))
(defun my-draft-latex (&optional async subtreep visible-only body-only
ext-plist)
(interactive)
(let ((outfile (org-export-output-file-name ".tex" subtreep)))
(if async
(org-export-async-start
(lambda (f) (org-export-add-to-stack f 'e-latex))
`(expand-file-name
(org-e-latex-compile
(org-export-to-file
'my-draft-latex ,outfile ,subtreep ,visible-only ,body-only
',ext-plist))))
(org-e-latex-compile
(org-export-to-file
'my-draft-latex outfile subtreep visible-only body-only
ext-plist)))))
#+end_src
Note that if you don't want the hassle of creating a derived back-end,
you can also implement a function that will remove every section
containing only sections or nothing from the buffer, and add it to
`org-export-before-processing-hook' (or
`org-export-before-parsing-hook').
