Hi Z,

I do something similar in my ox-leanpub-book module [1], which exports each
top-level heading to a different file. The general idea is to use
=org-map-entries= to loop over the entire buffer [2]. The function you call
can then check whether the current entry is a header at the level you want
[3] and then export it to the corresponding file. The title can be used to
deduct the filename [4].

I found that I had to mark the entire subtree before calling the export
function [5], otherwise the headline was not getting included in the export.

I based my code originally on this blog post, which might be a simpler
starting point:
https://medium.com/@lakshminp/publishing-a-book-using-org-mode-9e817a56d144
- this code does not select the entire subtree before exporting, which
means only the contents of the section is exported, but not the headline
itself.

Hope this helps!
