使用 beautifulsoup 从 HTML 中获取链接文本

Question

从下面的 HTML 示例部分，我使用 beautifilsoup 从页面中提取了一堆足球比分，很简单：

<tr class='report' id='match-row-EFBO695086'> <td class='statistics show' title='Show latest      match stats'> <button>Show</button> </td>  <td class='match-competition'> Premier League  </td>  <td class='match-details
teams'> <p> <span class='team-home teams'> <a href='/sport/football/teams/manchester-city'>Man City</a> </span>   <span class='score'> <abbr title='Score'> 1-0 </abbr> </span>   <span class='team-away teams'> <a
href='/sport/football/teams/crystal-palace'>Crystal Palace</a> </span>   </p> </td> <td class="match-date"> Sat 28 Dec </td>   <td class='time'>  Full time  </td>   <td class='status'>    <a class='report'
href='/sport/football/25474625'>Report</a>

from bs4 import BeautifulSoup
import urllib.request
import csv

url = 'http://www.bbc.co.uk/sport/football/teams/manchester-city/results/'
page = urllib.request.urlopen(url)
soup = BeautifulSoup(page)

for score in soup.findAll('abbr'):
    print(score.string)

>>> 
None
1-2 
1-0 
0-2 
2-1 
2-2 
4-1 
0-2 
1-1 

如何从这部分 HTML 中提取团队名称：

<span class='team-away teams'> <a href='/sport/football/teams/crystal-palace'>Crystal Palace</a>    </span> 

Answer 1

这个想法是首先获取包含每个游戏信息的元素 - 这些是带有class="report" 的tr 标签。对于每一行，按班级team-home 和team-away 获取团队名称，并按标签名称abbr 得分：

from bs4 import BeautifulSoup
import urllib.request

url = 'http://www.bbc.co.uk/sport/football/teams/manchester-city/results/'
page = urllib.request.urlopen(url)
soup = BeautifulSoup(page)

for match in soup.select('table.table-stats tr.report'):
    team1 = match.find('span', class_='team-home')
    team2 = match.find('span', class_='team-away')
    score = match.abbr
    if not all((team1, team2, score)):
        continue

    print(team1.text, score.text, team2.text)

打印：

Man City   1-2   CSKA 
Man City   1-0   Man Utd 
Man City   0-2   Newcastle 
West Ham   2-1   Man City 
...

仅供参考，table.table-stats tr.report 是一个CSS Selector，它匹配table 内的所有tr 标记和class="report" 和class="table-stats"。
