How to prepare an exported XML file from a MySQL database for import into Highload infoblocks?

Question

MySQL

Good evening.
What we do:
1) Export the MySQL database (with tables: akb, makes, models, modifications and vehicles) to an XML file. Each table has different columns!
2) In the XML file, you must make such a structure that the import will work correctly.
So. With the first task, I already solved the issue by exporting each table through PhpMyAdmin. The result is one of several files (for example, let's take the makes table ) : https://pastebin.com/raw/CMFhCrkq
Among the tables there is a fairly large one, consisting of 200,000 entries. After looking at all this, I realized that I needed to somehow automate the process of setting up the structure, so I am turning to you for suggestions. What do you think?
