从网站提取数据的代码存在问题

Question

我有这个网站，我想通过Python提取所有公司名称，如West Wood Events或Mitchell Event Planning。

但我被困在soup.find上，因为它导致了我的[]。当我检查页面时，让我们这样说：

< div class="LinesEllipsis  vendor-name--55315 primaryBold--a3d1e body1--24afd">Mitchell Event Planning<wbr></div >

我会写：

week = soup.find(class_='LinesEllipsis  vendor-name--55315 primaryBold--a3d1e body1--24afd')
print(week)

我得到0。

我是不是错过了什么？我对此很陌生。

Answer 1

这个字符串不是单个类，而是用空格分隔的多个类。

在一些模块中，你必须使用所有空格的原始字符串，但在BS中，你似乎必须使用由单个空格分隔的类。

如果我在LinesEllipsis和vendor-name--55315之间使用单个空格，则代码对我有效。

week = soup.find_all(class_='LinesEllipsis vendor-name--55315 primaryBold--a3d1e body1--24afd')

或者，如果我对字符串中的每个类使用带点的CSS选择器

week = soup.select('.LinesEllipsis.vendor-name--55315.primaryBold--a3d1e.body1--24afd')

最小工作代码

import requests
from bs4 import BeautifulSoup as BS
url = 'https://www.theknot.com/marketplace/wedding-planners-acworth-ga?page=2'
r = requests.get(url)
soup = BS(r.text, 'html.parser')
#week = soup.select('.LinesEllipsis.vendor-name--55315.primaryBold--a3d1e.body1--24afd')
week = soup.find_all(class_='LinesEllipsis vendor-name--55315 primaryBold--a3d1e body1--24afd')
for item in week:
print(item.text)

结果：
