循环遍历URL的Dataframe列并解析出html标记

import pandas as pd
import requests
from bs4 import BeautifulSoup

df = pd.DataFrame({'URL': ['url1', 'url2', 'url3']})

def parse_html(url):
    response = requests.get(url)  # 发送HTTP请求获取页面内容
    soup = BeautifulSoup(response.content, 'html.parser')  # 使用BeautifulSoup解析HTML
    # 在这里可以根据需要提取所需的HTML标记或数据
    # 示例：提取所有的<a>标签
    links = soup.find_all('a')
    for link in links:
        print(link.get('href'))

for url in df['URL']:
    parse_html(url)
