Python BS4抓取表在<td>标签中具有多个值

debugcn 发表于 Dev

以利

我正在尝试在标签中具有多个类的表上使用BS4。下面的示例HTML。

   </tr><tr id="_North_Carolina" class="seedrow">
<td title="Click to show/hide ranks" class='lowrowclick' style="text-align:center;font-size:8px">5</td>
<td  id='North_Carolina' class="teamname"><a href="team.php?team=North+Carolina&year=2019" style="text-decoration: none;">North Carolina<span class="lowrow" style="font-size:10px"><br/>&nbsp;&nbsp;&nbsp;1 seed, <span style='background-color:#BAE2C6'>Sweet Sixteen</span></span></a></td>
<td class="mobileout" style="text-align:center"><a href="conf.php?conf=ACC&year=2019">ACC</a></td>
<td class="6  mobileout" style="text-align:center">33</td>
<td class="5  " style="text-align:center;border-right:solid 1px black"><a title = "<b>Wins:</b> @ Wofford, @ Elon, Stanford, Tennessee Tech, St. Francis PA, v.

我的目标是从团队记录（td类5）开始，然后将其返回为：

North_Carolina, 30-3, 16-0

我当前的代码

data = soup.findAll('tr', class_ = 'seedrow')

    for item in data:
      records = item.find('td', class_ = '5')
      for first in records:
        reg_record = first.find('a')
        print(reg_record)

仅返回“无”列表。任何帮助将不胜感激。

您在锚标记中发布的html出现问题，因为href尚未关闭单引号。

就是这样<a title = "Wins" href='results.php? >。我已将其修改为<a title = "Wins" href='results.php?'>

这是我测试过的代码

from bs4 import BeautifulSoup
strrr = """<tr id="_North_Carolina" class="seedrow"><td class="5" style="text-align:center;border-right:solid 1px black"><a title = "Wins" href='results.php?'>30–3</a> <br/><span class="lowrow" style="font-size:8px;">16–0</span></td></tr>
"""
soup = BeautifulSoup(strrr, 'html.parser')
data = soup.findAll('tr', attrs={"class": "seedrow"})

for item in data:
    records = item.findAll('td', attrs={"class": "5"})
    for first in records:
        reg_record = first.find('a').contents[0]
        print(reg_record)

输出为30-3
