如何使用Python将XML中的所有信息都放入字典中

import xml.etree.ElementTree as ET

def xml_to_dict(xml_str):
    root = ET.fromstring(xml_str)
    return element_to_dict(root)

def element_to_dict(element):
    result = {}
    if len(element) == 0:
        return element.text
    for child in element:
        child_data = element_to_dict(child)
        if child.tag in result:
            if type(result[child.tag]) is list:
                result[child.tag].append(child_data)
            else:
                result[child.tag] = [result[child.tag], child_data]
        else:
            result[child.tag] = child_data
    return result

xml_str = '''
<root>
    <person>
        <name>John</name>
        <age>30</age>
    </person>
    <person>
        <name>Jane</name>
        <age>25</age>
    </person>
</root>
'''

result = xml_to_dict(xml_str)
print(result)

{
    'person': [
        {'name': 'John', 'age': '30'},
        {'name': 'Jane', 'age': '25'}
    ]
}
