python在解析HTML内容时使用剥离_strings时返回有关属性的错误.此HTML内容已添加到类中

Question

python在解析html内容时使用剥离的属性时返回有关属性的错误。此HTML内容已添加到类中。这是代码段，需要提取的数据是列表的一部分。

Updated Code : 

从输入导入列表中，任何可选

导入请求从BS4进口

Restapp类： def init (self，url(： self.url = url

def getAllUsers(self):
    # the list is added here
    data = '''<ul class="users-list clearfix">
                <li>

实际结果= attributeError：'nontype'对象没有属性'剥离'

Answer 1

您正在用字符串字面的 '''data'''构造美丽的小组，而不是变量data。

import requests
from bs4 import BeautifulSoup
class RESTApp:
    def __init__(self, url):
        self.url = url
    def getAllUsers(self):
        # the list is added here
        data = '''<ul class="users-list clearfix">
                <li>
                ...............
                </li>
                <li>
                ......
                </li>
                <li>
                .....
                </li>
            </ul>'''

        # parsing the data to get text from list.
        soup = BeautifulSoup(data, "html.parser")
        user_names = soup.find('ul', class_='users-list clearfix')
        split_details = list(user_names.stripped_strings)
        print(split_details)
test = RESTApp("https://adminlte.io/themes/AdminLTE/pages/examples/profile.html")
test.getAllUsers()

Answer 2

将 soup = BeautifulSoup('''data''', "html.parser")更改为 soup = BeautifulSoup(data, "html.parser")
