This looks solid and does the job, just make sure to do this:

• change the tests to return something with a guaranteed order, not maps whose items’ ordering is not guaranteed
• format Python code

[antepusic]

@antoniofilipovic The tests use example XMLs from a third-party website. Thinking about reliability, I think it’s better to make our own example XMLs and host them on some Memgraph repo.

@antepusic @antoniofilipovic shouldnt the map order always be same in tests?

[antepusic]

About map order: The map contains elements from children, whose value is taken from the ElementTree parsed by .fromstring.

result[children_name] = [
    parse_element(child, simple) for child in children
]

After checking, I think their ordering is consistent so the tests are fine in that respect.

@antepusic I wouldn't do that for now. If it starts failing, we can check then.
