translate_document_from_filepath fails to recognise XML files

[MasonLyons]

When trying to translate an xml document using the translate_document_from_filepath method an error is returned.

import deepl

input_filename = "test.xml"
source_language = "en"
output_filename = "test_out.xml"
output_language = "es"

translator = deepl.Translator(auth_key)
translator.translate_document_from_filepath(
    input_path=input_filename,
    output_path=output_filename,
    source_lang=source_language,
    target_lang=output_language,
)

Bad request, message: Failed to get the document_type from the file extension (test.xml).

Document translation does not support xml files, you would need to send it as a text translation request by using XML tag handling. See docs for document translation and XML tag handling (or check the README of this project regarding tag handling).

Edit: That said, we support HTML - I will check with the team if we can expand coverage here.
