Thanks for the suggestion. I pursued that a bit this weekend. The resulting data structure is a Circular Object[1] due to the ":parent" references. It seems dealing with this kind of data structure is somewhat uncommon (or my search-fu lacking), although I do find a recent reference to it on this mailing list[2]. I also found a "cust-print"[3] feature from Emacs 19 which has since been removed. It shows a way to deal with Circular Objects. So far it has strongly taxed my poor elisp skills but I plan to pursue this direction a bit more. I did try throwing a JSON parser/generator[4] at the output of org-element-parse-buffer but this failed due to exceeding emacs's recursion limits. I think this must be from the ":parent" references getting recursed on forever. -Brett.
