How to fix invalid xml file?

Question

JavaScript

There is an xml-file with duplication of several closing tags at the end of the file.
Can you please tell me a library that can correctly remove unnecessary tags?
Looking ahead, if I understand correctly, then for this you need to use a sanitizer \ sanitizer, but all the libraries that it finds are either in java or for HTML.

Answer 1

libxmljs
grunt-xml-validator
