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

问题描述

使用 BeautifulSoul 和 Python，我想find_all 匹配包含多个名称的给定类属性的所有 tr 项目，如下所示:

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   ">

我尝试了多种方法来匹配该类.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.

有什么方法可以使用正则表达式、通配符或者如何匹配这个类?

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

在这里发布了同样的问题没有答案.

推荐答案

您可以使用 css 选择器 匹配多个类:

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>]
