使用python将html数据转换为json
使用python将html数据转换为json
提问于 2022-09-21 23:18:03
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

你试过这样的东西吗？只需查找要查找的元素？https://www.w3schools.com/python/gloss_python_json_parse.asp即可。
蟒蛇的文档可能也有帮助..。https://docs.python.org/3/library/json.html
请问您为什么要将HTML编码为JSON？

--好吧，如果有人想要一个解决方案，我用下面的逻辑来解决它
from html_to_draftjs import html_to_draftjs
import bleach,json
from bleach.css_sanitizer import CSSSanitizer
def htmltodraftjson():
with open("WorkStatement.html", "r") as html_file:
html = html_file.read()
css_sanitizer = CSSSanitizer(allowed_css_properties=["color", "font-weight"])
output_json = html_to_draftjs(bleach.clean(html,tags=['div', 'p', 'ul', 'ol', 'blockquote', 'h1', 'h2', 'h3', 'h4', 'h5', 'h6', 'strong', 'b', 'em', 'i', 'img', 'a', 'br'], strip=True))
with open('WorkStatement.json', 'w') as outfile:
json.dump(output_json, outfile,indent=4)
