问 使用python将html数据转换为json

EN

我尝试使用下面的代码将html文件数据转换为json。

import html_to_json
import json
def htmltojson():
    with open("C:\Extraction\Sample.html", "r") as html_file:
        html = html_file.read()
        output_json = html_to_json.convert(html,capture_element_attributes=False,capture_element_values=True)
    with open('Final.json', 'w') as outfile:
        json.dump(output_json, outfile,indent=4)
        print(output_json)

我得到的json包含html、span和其他标记，我只想要键和它的值。

Json输出我得到了

预期的输出是某种形式。

示例预期格式

[{“键”："1“、”值“：”子“：”[] }、{“键”："2“、”值“：”子“：[{”键“："2.1”、“值”：“子”：[] }、{“键”："2.2“、”值“：”子“：”子“：[ }{“键”："3"，“值”：“子”：[{“键”："2.1"，“值”：“子”：[{“键”："2.1.1"，“值”："“子”：[ } ]}}]
