beautiful soup findall multiple class using one query

问题

I searched thoroughly for solution on many websites and on here but none of them works!

I am trying to scrape flashscores.com and i want to parse a <td> with the class name cell_ab team-home or cell_ab team-home bold

I tried using re

soup.find_all('td', { 'class'= re.compile(r"^(cell_ab team-home |cell_ab team-home  bold )$"))

and

soup.find_all('td', { 'class' : ['cell_ab team-home ','cell_ab team-home  bold '])

neither of them works.

someone requested for the codes so here it is

 from tkinter import *
 from selenium import webdriver
 import threading
 from bs4 import BeautifulSoup

 browser = webdriver.Firefox()
 browser.get('http://www.flashscore.com/')

 HTML = browser.page_source
 soap = BeautifulSoup(HTML)
 for item in soap.find_all('td', class_ = ['cell_ab team-home ','cell_ab team-home  bold ']):
        Listbox.insert(END,item.text)

回答1:

The bs4 documentation says the following about matching using class_:

Remember that a single tag can have multiple values for its class attribute. When you search for a tag that matches a certain CSS class, you’re matching against any of its CSS classes.

According to the documentation, you'd have to use CSS selectors here, with the .select method. Thus something like this ought to do the trick:

soup.select('td.cell_ab.team-home')

This would select all <td>s that have both cell_ab and team-home classes set, including <td>s that have additional classes, such as bold.

You can use re to find it:

soap.findAll('td', {'class' : re.compile('cell_ab team-home '|'cell_ab team-home  bold ')})

This will find tag td with class='cell_ab team-home' and tag td with clas='cell_ab team-home bold'

回答3:

you can use a list sitax, like:

soup.findAll('td', {'class':['cell_ab team-home', 'cell_ab team-home  bold ']})

回答4:

you can use selector like this:

soup.select('.cell_ab.team-home')
