我安装了BeautifulSoup，阅读了文档并找到了一些关于从表中获取信息的教程，但只从基本表中添加了几行和列。 我无法理解如何做更复杂的事情。
我有一个HTML文档并使用
table = soup.findAll("table")
找到桌子。我得到的是一堆看起来像这样的列表：
<tbody class="item" data-buyout="8 exalted" data-ign="POOPOODOODOO" data-league="Standard"
data-name="Dusk Stone Cobalt Jewel" data-seller="LooseSausage" data-sellerid="3447078"
data-thread="1285903" id="item-container-0">

我想做的是采用数据买断，数据点击，数据名称等部分，并将它们保存在变量中以供日后使用。然后跳到li class =“sortable”并获取数据名称部分或文本。 （因为它们似乎是一样的）
我无法理解如何在tbody class =“item”部分内完成所有操作。
我需要多次这样做，因为每个表中有多个带有tbody class =“item”的项目。
非常感谢我能得到的任何信息！
答案 0 :(得分：1)
您可以获得如下数据：
from bs4 import BeautifulSoup
soup = BeautifulSoup(your_string_above)
>>>soup.tbody.attrs
{'data-sellerid': '3447078', 'data-buyout': '8 exalted', 'data-league': 'Standard', 'data-name': 'Dusk Stone Cobalt Jewel', 'data-thread': '1285903', 'id': 'item-container-0', 'data-ign': 'POOPOODOODOO', 'data-seller': 'LooseSausage', 'class': ['item']}
>>>[x.get_text(strip=True) for x in soup.select('li')]
['4% increased Attack SpeedMinions have10% increased maximum Life5% increased Ignite Duration on EnemiesMinions deal16% increased Damage2% chance to Ignite', '4% increased Attack Speed', 'Minions have10% increased maximum Life', '5% increased Ignite Duration on Enemies', 'Minions deal16% increased Damage', '2% chance to Ignite']
