在 Beautifulsoup 中查找特定的 HTML 标签

Question

我已经尝试了几个小时来找到正确的 soup.select_one 或 find_next 组合来找到下面的 zestimate 标签。你能帮忙找到这个汤代码吗？

这是网址：

https://www.zillow.com/homedetails/8612-Silverthorne-St-Austin-TX-78744/251036192_zpid/

我正在尝试返回： $486,997

    print(results)

Answer 1

基于my answer：Zillow 为用户提供的页面类型似乎更多。首先检查，如果你没有得到验证码页面。如果没有，请使用此脚本：

import requests
from bs4 import BeautifulSoup


url = 'https://www.zillow.com/homedetails/8612-Silverthorne-St-Austin-TX-78744/251036192_zpid/'
headers = {'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:77.0) Gecko/20100101 Firefox/77.0'}
soup = BeautifulSoup(requests.get(url, headers=headers).content, 'html.parser')

home_value = soup.select_one('h4:contains("Home value")')
if not home_value:
    home_value = soup.select_one('.zestimate').text.split()[-1]
else:
    home_value = home_value.find_next('p').get_text(strip=True)

print(home_value)

打印：

$486,997

对于url = 'https://www.zillow.com/homedetails/1404-Clearwing-Cir-Georgetown-TX-78626/121721750_zpid/'，它会打印：

$324,493

可能需要更多测试。
