我试图从下面给出的网站中提取此表：
https://bills.parliament.nz/bills-proposed-laws?Tab=All&Period=0&To=2023-05-22&From=2018-01-01&SelectCommittee=a0f103be-0902-4480-9778-93a5229dca71
下面是我的代码：

import requests
from bs4 import BeautifulSoup
import pandas as pd
a = requests.get('https://bills.parliament.nz/bills-proposed-laws?Tab=All&Period=0&To=2023-05-22&From=2018-01-01&SelectCommittee=a0f103be-0902-4480-9778-93a5229dca71')
a.status_code
soup = BeautifulSoup(a.content, 'html.parser')
table2 = soup.find("div", class_="d-none d-lg-block")
print(table2)
# Output --> 
#[]

使用bs 4，我尝试提取表。

我也试过使用xpath，但没有成功。
任何帮助将不胜感激！

您不能直接使用requests进行提取，因为内容是动态加载的。但是，您可以使用他们的API：

payload = {  # all parameters
   'id': None,
   'documentPreset': 1,
   'keyword': None,
   'selectCommittee': 'a0f103be-0902-4480-9778-93a5229dca71',

   'pageSize': 10,
   'page': 1
}

url = 'https://bills.parliament.nz/api/data/search'

data = requests.post(url, json=payload).json()

输出：
