如何将子节点和子元素从xml转换为json

import xml.etree.ElementTree as ET
import json

def xml_to_json(xml_string):
    root = ET.fromstring(xml_string)
    json_data = traverse_element(root)
    return json.dumps(json_data)

def traverse_element(element):
    json_data = {}
    json_data['tag'] = element.tag
    json_data['attributes'] = element.attrib
    json_data['text'] = element.text

    children = list(element)
    if children:
        json_data['children'] = [traverse_element(child) for child in children]
    return json_data

# 示例XML字符串
xml_string = '''
<root>
    <person>
        <name>John</name>
        <age>30</age>
    </person>
    <person>
        <name>Jane</name>
        <age>25</age>
    </person>
</root>
'''

# 转换为JSON字符串
json_string = xml_to_json(xml_string)
print(json_string)

{
  "tag": "root",
  "attributes": {},
  "text": "\n    ",
  "children": [
    {
      "tag": "person",
      "attributes": {},
      "text": "\n        ",
      "children": [
        {
          "tag": "name",
          "attributes": {},
          "text": "John"
        },
        {
          "tag": "age",
          "attributes": {},
          "text": "30"
        }
      ]
    },
    {
      "tag": "person",
      "attributes": {},
      "text": "\n        ",
      "children": [
        {
          "tag": "name",
          "attributes": {},
          "text": "Jane"
        },
        {
          "tag": "age",
          "attributes": {},
          "text": "25"
        }
      ]
    }
  ]
}
