解析这个嵌套的 json？

Question

我正在尝试解析从 xml 转换为 json 的 nmap 扫描结果。 json 我无法提取的部分内容如下：

"ports": {
    "port": {
    "@portid": "22",
    "state": {
        "@state": "open",
    },
    "service": {
        "@product": "OpenSSH",
    },
    "script": [
        {
            "@output": "\n  ssh-dss AAAArO379Amw==\n  ssh-rsa AAAAB3nSb3vZeQAw==",
            "@id": "ssh-hostkey",
            "table": [
                {
                    "elem": [
                        {
                            "@key": "key",
                            "#tail": "\n",
                            "#text": "QUFBQUIzTnphQzFrYzNNQUFBQ0JBUHkzQVhaemI4N1IzRvQnh3ZWlOaJtLzc1azBsMGtVMG1ock8zNzlBbXc9PQ=="
                        },
                        {
                            "@key": "fingerprint",
                            "#tail": "\n",
                            "#text": "4724ad3b5f2"
                        }
                    ],
                    "#tail": "\n",
                    "#text": "\n"
                },
                {
                    "elem": [
                        {
                            "@key": "key",
                            "#tail": "\n",
                            "#text": "QUFBQUIzTnphQzF5YzJFQUFBQUJJd0FBQVFFQXJlZTc5cWhlNUJxQ3RPWElYbDVrbTY0azI5eHR3UStyTnRiM3ZaZVFBdz09"
                        },
                        {
                            "@key": "fingerprint",
                            "#tail": "\n",
                            "#text": "a015719c9"
                        }
                    ],
                    "#tail": "\n",
                    "#text": "\n"
                }
            ]
        }}}

我正在尝试从脚本键中提取部分，我的代码如下所示

if 'script' in extracted_json['ports']['port']:
    for something in extracted_json['ports']['port']['script']['table']:
        print something['elem']

然而，当我运行它时，我收到错误消息 TypeError: string indices must be integers。如果我尝试将 print 语句更改为 print something[1]，那么我会得到：KeyError: 1。我应该如何从这个嵌套的 json?

中提取信息

变量某物包含这个

{
    u '#tail': u '\n', u '#text': u '\n', u 'elem': [{
        u '#tail': u '\n',
        u '@key': u 'key',
        u '#text': u 'QUFBQUIzTnTVaWURiMFNpdz09'
    }, {
        u '#tail': u '\n',
        u '@key': u 'bits',
        u '#text': u '2048'
    }, {
        u '#tail': u '\n',
        u '@key': u 'fingerprint',
        u '#text': u '239d68c0c083446c'
    }, {
        u '#tail': u '\n',
        u '@key': u 'type',
        u '#text': u 'ssh-rsa'
    }]
}

Answer 1

script包含一个数组，需要循环遍历。而table也是一个数组。

for script in extracted_json['ports']['port']['script']:
    for table in script['table']:
        print table['elem']

解析这个嵌套的 json？

Parsing this nested json?
