Hi @naboeita92,
Thanks for clarifying. For future questions, please try to limit your posts to one topic per post - this helps keep the forum more tidy and focuses post on one particular issue, which can be more beneficial for users who might learn from these posts.
With respect to the XML import however, yes importing the full text of the files is doable. I’d recommend having a look at the example XML here: test 1
This post also gives some helpful advice on linking to files that you’d import via native XML: Importing PDFs from remote URL with Native XML Plugin - #3 by bibliothekswelt
