Hi Marvin, I replied to a similar question some time ago, here's my answer (with updated links since the files have changed in the meantime):
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. I wrote a simplified function which puts the above ideas together, feel free to use it: https://gist.github.com/zzamboni/2e6ac3c4f577249d98efb224d9d34488 Hope this helps! --Diego [1] https://github.com/zzamboni/ox-leanpub/tree/book-and-markua [2] https://github.com/zzamboni/ox-leanpub/blob/f7ae0f86f517a321a5150e1c712554b12acf144b/ox-leanpub-book.el#L216-L217 [3] https://github.com/zzamboni/ox-leanpub/blob/f7ae0f86f517a321a5150e1c712554b12acf144b/ox-leanpub-book.el#L145 [4] https://github.com/zzamboni/ox-leanpub/blob/f7ae0f86f517a321a5150e1c712554b12acf144b/ox-leanpub-book.el#L154-L158 [5] https://github.com/zzamboni/ox-leanpub/blob/f7ae0f86f517a321a5150e1c712554b12acf144b/ox-leanpub-book.el#L192 On Sat, May 30, 2020 at 12:08 PM Marvin M.
