如何从json中提取包含父兄弟和子字符串的文本？

import json

def extract_text_from_json(json_data, target_substring):
    extracted_text = []
    
    # 解析JSON数据
    data = json.loads(json_data)
    
    # 遍历JSON数据
    def traverse(data, parent_key=''):
        if isinstance(data, dict):
            for key, value in data.items():
                # 检查键是否包含目标子字符串
                if target_substring in str(key):
                    extracted_text.append(key)
                
                # 检查值是否包含目标子字符串
                if target_substring in str(value):
                    extracted_text.append(value)
                
                # 递归遍历子对象
                traverse(value, parent_key=key)
        elif isinstance(data, list):
            for item in data:
                # 递归遍历列表中的元素
                traverse(item, parent_key)
    
    traverse(data)
    
    return extracted_text

# 示例JSON数据
json_data = '''
{
    "name": "John",
    "age": 30,
    "siblings": ["Jane", "Bob"],
    "address": {
        "street": "123 Main St",
        "city": "New York",
        "country": "USA"
    }
}
'''

# 提取包含父兄弟和子字符串的文本
target_substring = "ob"
result = extract_text_from_json(json_data, target_substring)
print(result)

['Bob', 'siblings']
