Hello Orgers,
assume that I have this in my Org file:
#+BEGIN_FOO :bar baz qux
whatever
#+END_FOO
and I want to extract the value of the header argument "bar" (i.e., the
string "baz qux" in this case). How do I do it? (I'm writing – still –
the custom exporter, and would like to be able to set something
spearately for each special block of some kind.)
BTW, a shameless plug: while Org-edu-HTML
(https://github.com/mbork/org-edu-html) is not yet production-ready, it
was nevertheless used for a real life project, and it seems to be
working (despite some rough edges). Let me remind you that it is an
HTML exporter for educational materials (currently: single and multiple
choice tests, cloze tests and “show the answer” buttons). In case any
of you finds this interesting, all feedback is welcome.
TIA,

Here's something to get you started.
#+BEGIN_FOO :bar baz qux
whatever
#+END_FOO
#+BEGIN_SRC emacs-lisp
(goto-char (point-min)) ; to make the example work
(let ((str (and (search-forward-regexp org-block-regexp nil t)
(match-string 3))))
(when str
(string-match "[ \t]:\\w+[ \t]+\\([^:]+\\)" str)
(org-trim (match-string 1 str))))
#+END_SRC
#+RESULTS:
: baz qux
There's a similar "parser" in org-export-expand-include-keyword. If you
know which argument you are looking for you can replace the \\w+ above.
Hope it helps,
Rasmus

It will be easier to use a src block for a faux language (say FOO).
Customize `org-babel-execute:FOO' as needed and you should be set:
#+BEGIN_SRC emacs-lisp
(defun org-babel-execute:FOO (body params &optional etc)
(concat body (format " %S" (assoc :bar params))))
#+END_SRC
#+RESULTS:
: org-babel-execute:FOO
#+NAME: example1
#+BEGIN_SRC FOO :bar baz qux :exports results
whatever
#+END_SRC
#+RESULTS: example1
: whatever (:bar . "baz qux")
HTH,
Chuck
