有没有办法在bs4中抓取div ID?

标签: python beautifulsoup

有多个div类,它们具有相同的类名,但ID不同:

<div class ="starting-lineups__matchup" data-gamepk="******">

我能够在这些类中抓取所需的数据,但我一直不得不检查页面以找出data-gamepk的值。有没有办法刮这个号码?

这是我要抓取的网站,下面是我的代码:

https://www.mlb.com/starting-lineups

#main table that contains the data
gamelist = soup.find('div',attrs={'class':'starting-lineups__container-multi'})

user = input()

#game specific data
game = gamelist.find('div',attrs={'data-gamepk':user})

#loop through away team name
for teams in game.find_all('span',attrs={'class':'starting-lineups__team-name--away'}):
    for team_a in teams.find_all("a"):
        print(team_a.text)

因此,所有名为'starting-lineups__matchup'的类都在'starting-lineups__container-multi'类之内。所有'starting-lineups__matchup'类都有一个与之关联的数字。用户手动输入此数字可将特定类别中的数据抓取。上面的代码中,哪一个只是客队名称starting-lineups__team-name--away

为了找到每个游戏的编号,我一直在检查网页。不必亲自访问该网站并亲自浏览html,我想抓取该数字以及与之相关的团队名称。

您也许可以使用此功能:

from bs4 import BeautifulSoup import re

soup= BeautifulSoup(html.text,'lxml') 
results = soup.findAll("div", {"data-gamepk" : re.compile(r".*")})

这将列出每个具有“ data-gamepk”属性的div。

PS:使用True代替re.compile(r“。*”)可能也可以。

希望我能正确理解您的问题:此脚本将打印游戏编号和主队/客队名称:

import requests
from bs4 import BeautifulSoup


url = 'https://www.mlb.com/starting-lineups'
soup = BeautifulSoup(requests.get(url).content, 'html.parser')

for game in soup.select('[data-gamepk]'):
    print(game['data-gamepk'])
    print(game.select_one('.starting-lineups__team-name--away').get_text(strip=True))
    print(game.select_one('.starting-lineups__team-name--home').get_text(strip=True))
    print('-' * 80)
