如何在python中使用request和beautifulsoup搜索多个预定义的字符串

pip install requests
pip install beautifulsoup4

import requests
from bs4 import BeautifulSoup

def search_predefined_strings(strings):
    url = "https://example.com"  # 替换为要搜索的网页的URL
    response = requests.get(url)
    soup = BeautifulSoup(response.content, "html.parser")

    for string in strings:
        elements = soup.find_all(text=string)
        if elements:
            print(f"找到预定义字符串 '{string}'：")
            for element in elements:
                print(element)
        else:
            print(f"未找到预定义字符串 '{string}'")

predefined_strings = ["字符串1", "字符串2", "字符串3"]  # 替换为预定义的字符串列表
search_predefined_strings(predefined_strings)
