Hi!
Create the tables you think you would need in your database.
Then insert the parsed xml’s into your tables.
That’s not the difficult part, you have activities for doing SQL in this package https://docs.uipath.com/activities/other/latest/user-guide/about-the-database-activities-pack
The difficult part is parsing your xml’s into datatables (All about Datatable - UiPath) before you insert them into your database.
