BeautifulSoup和带有空格的类 [英] BeautifulSoup and class with spaces

问题描述

使用BeautifulSoul和Python，我想find_all匹配与给定类属性匹配的所有tr项目，该给定类属性包含多个这样的名称:

With BeautifulSoul and Python, I want to find_all all the tr items matching a given class attribute that contains multiple names like this one:

<tr class="admin-bookings-table-row bookings-history-row  paid   ">

我尝试了几种匹配该类的方法.正则表达式，通配符，但我总是得到一个空列表.

I have tried several ways to match that class. Regular expressions, wildcards but I always get an empty list.

是否可以使用正则表达式，通配符或如何匹配此类?

Is there any way to use regular expressions, wildcards or how to match this class?

在此处发布了相同的问题没有答案.

推荐答案

您可以使用

you can use a css selector to match many classes :

from bs4 import BeautifulSoup as soup
html = '''
<tr class="admin-bookings-table-row bookings-history-row  paid   "></tr>
<tr class="admin-bookings-table-row  nope  paid   "></tr>
'''
soup = soup(html, 'lxml')

res = soup.select('tr.admin-bookings-table-row.bookings-history-row.paid')
print(res)

>>> [<tr class="admin-bookings-table-row bookings-history-row paid "></tr>]
