The lower-level library is used in Odoo ERP for example. Possibly others, as there are a few implementations[1] (mostly Java). This is lots of work because you need to create the XML yourself. I tried to make mappings between simple keywords and the XPaths of different XML standards (there are a bunch)[2]
So in theory you could just give a few keywords and get the full XML. Currently this is on hold, but if someone has a use case and wants to contribute, I'd be happy to continue working on it. I also provide this other library[3] that extracts some essential data from PDFs. The plan is to use them together to automatically build the XML from just the PDF.
Thank you! I will look into these. I know the problems. As i was working in the accounting firm i was dealing with imports/exports from various accounting softwares a lot. In fact i'm currently working on an app which can convert between them as my side project.
