从网站中提取数据的代码存在问题

Question

我有this website，我想通过Python提取所有公司名称，如West Wood Events或Mitchell Event Planning

但是我被困在soup.find上，因为它导致了我[]。 当我查看页面时，让我们这样说：

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

在这方面，我将写：

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

print(week)

我得到了0

我错过什么了吗？我对这个很陌生

Answer 1

此字符串不是单个类，而是由空格分隔的多个类

在某些模块中，您必须将原始字符串与所有空格一起使用，但在BS中，您似乎必须使用由单个空格分隔的类

如果在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:
