当BeautifulSoup4中存在多个重复项时，如何指定所需的<table class>？

Question

所以基本上，我用的是

import requests
from bs4 import BeautifulSoup 

url='https://bn.mappersguild.com/'

headers={"User-Agent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.130 Safari/537.36'}

page = requests.get(url, headers=headers)


soup = BeautifulSoup(page.content, 'html.parser')
row = soup.find("table", {"class": "table table-sm table-dark table-hover col-6 col-md-3"}).get_text()

为了从下面的<td>taiko</td>下获取第二个列表

 <table class="table table-sm table-dark table-hover col-6 col-md-3">
                <thead>
                    <td>catch</td>

    ```
but bs4 keeps giving me the first list, how can I specify which duplicate I want?

Answer 1

您可以使用正在查找的文本找到<td>，然后使用find_parent从那里转到父表

title = soup.find('td', string='taiko')
row = title.find_parent("table", {"class": "table table-sm table-dark table-hover col-6 col-md-3"}).get_text()
print(row)

输出：

taiko
