python - python json从找到的元素中捕获整个节点

问题描述

我正在加载 json 并尝试提取一部分。我可以很好地加载json并查询它。我坚持检索它在其中找到的 json 节点。

所以我有一个像下面这样的 json 结构。我将如何寻找一个元素并捕获它的整个节点。即 name="7004389c-c47a-4611-9bd7-9f5dfe051d17" 然后返回以下内容： OUTPUT 示例：

{
            "name": "7004389c-c47a-4611-9bd7-9f5dfe051d17",
            "children": [],
            "behaviors": [
              {
                "name": "xxx",
                "options": {
                  "key": "xxx-xxx-xxx-xxx",
                  "compress": true,

                }
              }
            ],
            "criteria": [
              {

解决方案

您可以根据以下键搜索特定字典name：

# assuming test contains your json data
key = '7004389c-c47a-4611-9bd7-9f5dfe051d17'
res = [node for node in test["rules"]["children"][0]['children'] if node['name'] == key][0]

输出：

{'name': '7004389c-c47a-4611-9bd7-9f5dfe051d17', 'children': [], 'behaviors': [{'name': 'xxx', 'options': {'key': 'xxx-xxx-xxx-xxx', 'compress': True, 'ports': ''}}], 'criteria': [{'name': 'xxxx', 'options': {'Name': 'UUID', 'values': ['7004389c-c47a-4611-9bd7-9f5dfe051d17']}}], 'criteriaMustSatisfy': 'all'}
