How to rename xml tags?

Question

XML

Hello, I really need help with changing the tag name.
Since the import module on the site perceives the tag as param1, param2, param3 ... and the products in the file have a different structure of these tags, for example:
one product has param1 and the second param1, it will be too expensive to change the structure, since there are a very large number of parameters , therefore I see only one solution - to make a replacement through Notepad ++ or something else ... I will be very grateful for any help!
