Sure, I remember this thread and it is clear that the problem is very different when it is for LaTeX of for and HTML backend.
However, Reftex is provided with Emacs, and it is also integrated to Org mode.
So I was trying to solve my simple problem about the bibliography keyword this way:
(defadvice org-latex-keyword (around org-latex-keyword-bibliography)
"Exports `bibliography' keyword with LaTeX backend."
(let ((key (org-element-property :key (ad-get-arg 0)))
(value (org-element-property :value (ad-get-arg 0))))
(if (and (string= key "BIBLIOGRAPHY")
(string-match "\\(\\S-+\\)[ \t]+\\(\\S-+\\)\\([^\r\n]*\\)" value))
(let ((bibfile (match-string 1 value))
(bibstyle (match-string 2 value)))
(format "\\bibliography{%s}\n\\bibliographystyle{%s}" bibfile bibstyle))
ad-do-it)))
(ad-activate 'org-latex-keyword)
in my personal Org mode setup. However, it does not work. The advice is called and returns the string,
but somehow it is not inserted in the buffer. If I do the same thing in ox-latex.el:org-latex-keyword function,
it does work. Any idea why ?
