Re: [O] Include heading title in HTML section-number cross-reference, li

Excellent -- that seems to export just fine.  

Interestingly, the export now generates the message, "Position saved to mark ring, go back with C-c & ."  I presume that comes from the ((org-link-search-inhibit-query t)) argument in the "let" function.  It doesn't seem to harm the export results. 

One of these years I'll have to start poking around the Emacs-Lisp code to try to puzzle out the workings of the functions being called, especially 
--- is there a comparable one (or arguments) to get the section number of a heading?

Many thanks, Nicolas.

The following should work.

  #+MACRO: get-title (eval (or (save-excursion (ignore-errors (let ((org-link-search-inhibit-query t)) (org-open-link-from-string "[[#$1]]") (org-get-heading nil nil)))) "/$1/"))
