Actually both parsed.text and text_position are None. Look:

In [41]: parsed.__dict__
Out[41]: 
{'source': '<resources/>\n',
 'start': 0,
 '_position': 0,
 '_tag': 'resources',
 '_attrib': {},
 '_attrib_string': '',
 '_attributes': [],
 '_text_position': None,
 '_text': None,
 '_content_end': openformats.utils.xml.NewDumbXml.NOT_CACHED,
 '_tail_position': 12,
 '_tail': openformats.utils.xml.NewDumbXml.NOT_CACHED}

In [40]: first_tag_position = parsed.text_position + 0
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
Cell In [40], line 1
----> 1 first_tag_position = parsed.text_position + 0

TypeError: unsupported operand type(s) for +: 'NoneType' and 'int'

As you see from the above dumped parsed object the template is empty! The resource https://www.transifex.com/careem-1/ridehail-android/translate/#ur/features_ridehail_ui doesn't contain any strings. So I believe we are safe to put it like:

if parsed.text and parsed.text_position:
  first_tag_position = parsed.text_position + len(parsed.text)
  self.transcriber.copy_until(first_tag_position)

The rest of the compile() method code will run without errors...
