Finally coming back to this.
It seems that the actual string-with-properties may be nested at different
levels within the :caption object. I tried Nick's version with a different
test file, and it failed with a wrong type error.
The "while" below seems to work, though I suppose it could throw an error
under some circumstances.
Is there an easier way to locate the real stringy-thingy in the middle of
the structure, when you can't predict exactly what the structure will be?
(defun hjh-print-src-blocks ()
"Iterate src blocks from org-element and print them to *Messages*."
(interactive)
(let ((tree (org-element-parse-buffer)))
(org-element-map tree 'src-block
(lambda (element)
(setq element (car (cdr element)))
(let ((caption (plist-get element :caption)))
(while (and caption (not (stringp caption)))
(setq caption (car caption)))
(message "\n\n\nCAPTION:")
(print (substring-no-properties caption)))))))
hjh
