Can you provide an example of a JATS XML file for OJS?

Hello, I’m using OJS version 3.3.0.7 and encountering validation errors in the JATS XML files I’ve prepared.

I assume there are errors in the XML codes of the articles. Could you please provide me with a sample XML file or the specification of JATS XML?

How can I prepare correct JATS XML and XSD files?

Thank you!
