Hi list,
I'm writing a function which does some (serious) modifications on an Org
file. I want it to save the results in some new file, so I'm (most
probably) going to create a new buffer, execute (org-mode) there, copy
the contents of the old one (insert-buffer-substring?) and then do my
stuff.
However, "my stuff" depends on the (org) structure. Is there something
I should call /before/ I do (org-element-parse-buffer)? I want to do
something like
(org-element-map (org-element-parse-buffer) '(headline)
#'my-stuff)
Is that going to work reliably (on a newly-created buffer)?
TIA,

You probably need to copy the contents before calling `org-mode' so it
can properly initialize buffer local variables (e.g., #+TODO keywords).

(org-element-map (org-element-parse-buffer 'headline) 'headline
...)
will be much faster.
However, a better option may be to use `org-map-entries', which is more
robust wrt buffer modifications.
OTOH, `org-element-parse-buffer' should be considered if #'my-stuff
operates on the AST. Then you would insert
(org-element-interpret-data ast)
in the new buffer.

`org-element-parse-buffer' needs Org mode to be initialized.
