Thanks Nocolas. I need to copy only a subtree associated with a
headline. In a nutshell I need to "flatten" the tree of headlines for
the csv type exporter. That is, I need to replicate the parent headlines
across the children. For example
* H1
bla bla
** HA
some text
** HB
some other text
would translate into
* H1
bla bla
** HA
some text
* H1
bla bla
** HB
some other text
I played with org-element-extract-element, org-element-set-contents and
org-element-insert-before but failed a big deal.
Main problem seems to be the lack of uniform interface to handle parents
in connection to secondary elements (which I don't understand at this
point). Is headline a secondary element?
The :parent seems to be stored in 2 places for the headline, in the
headline itself and in the :title. Most of the org code uses
org-element-put-property and org-element-property to access the parent
but some code like org-element-extract-element uses :parent from
:title. This makes it difficult to program as there are no explicit
getter/setter for the parent.
BTW, is there a way to pretty print the org tree? I think that's the
main barrier for me in understanding how it all works.
Thanks,
Vitalie
