        elif isinstance(obj, xml.etree.ElementTree.Element) and isinstance(key, str):
            xpath, sep, special = key.rpartition('/')
            has_specials = special.startswith('@') or special == 'text()'
            if not has_specials:
                xpath = f'{xpath}{sep}{special}'

            # Allow abbreviations of relative paths, absolute paths error
            if xpath.startswith('/'):
                xpath = f'.{xpath}'
            elif xpath and not xpath.startswith('./'):

Review comment (suggestion):
```suggestion
                if special == '@':
                    return element.attrib
                elif special.startswith('@'):
                    return try_call(element.attrib.get, args=(special[1:],))
                elif special == 'text()':
                    return element.text
```

just for clarity
