我正在使用BeautifulSoup4抓取页面，并且以下功能给了我2个问题：
def getTeamRoster(teamURL):
html = urllib.request.urlopen(teamURL).read()
soup = BeautifulSoup(html)
teamPlayers = []
#second table
corebody = soup.find(id = "corebody")
teamTable = corebody.table.next_sibling.next_sibling.next_sibling.next_sibling
print(teamTable)
tableBody = teamTable.find('tbody')
print(tableBody)
tableRows = tableBody.findAll('tr')
1）当我仅调用4次“ .next_sibling”（如上所述）时，我似乎得到了正确的表。但是，我尝试访问的表标签是#corebody ID中的第6个表。当我调用“ .next_sibling” 5次时，我从BeautifulSoup得到-1，表明我请求的表不存在？我以为您通常会在这种情况下使None退回。知道为什么调用“ .next_sibling” 5次不能按预期工作吗？
网址为 http://modules.ussquash.com/ssm/pages/leagues/Team_Information.asp?id=11325
2）tableBody = teamTable.find（'tbody'）给我带来了一些麻烦。当我打印tableBody时，我没有任何提示，但是我不确定为什么会发生这种情况（我正在访问的表中肯定有一个标签）。
有想法吗？
感谢您的帮助，bclayman
我可以使用pandas.read_html以下方法获取玩家表：
import requests
import pandas as pd
url = 'http://modules.ussquash.com/ssm/pages/leagues/Team_Information.asp?id=11325'
tables = pd.read_html(requests.get(url).content)
