如何在python中使用beautifulsoup查找第n个子标题并打印文本

Question

根据我的代码，我可以获得项目的第一个标题，并且我希望打印副标题（FSI 详细信息）。无法使用 beautifulsoup 获得第二个标题。我尝试了第 n 个孩子的参考

您可以尝试 CSS 选择器:contains("FSI Details")，它选择包含字符串“FSI 详细信息”的元素。此代码打印“FSI 详细信息”部分的标签和值：

import requests
from bs4 import BeautifulSoup

url = 'https://maharerait.mahaonline.gov.in/PrintPreview/PrintPreview?q=BPUvrrjIzYs%2f2hwYj1YIOfflh9NisZW6zTns2KLjHBZn6cbQ008s91nzlFrDxVvLwR1vAeLID0%2bo%2bD0H0Z6o2t%2b5P%2b%2fbBOcHCbMQHU8gkwdNZJnbbfu6N7mWSpgKXt4AiQyzuEpoDE7FX6HZypqsGXz4ObYD4KpyRzCsFJaWTgA%3d'

soup = BeautifulSoup(requests.get(url).text, 'lxml')

fsi_content = soup.select_one('.x_title:contains("FSI Details") + .x_content')

print('{: <160}{: <8}'.format('Label', 'Value'))
print('-' * 168)
for label, text in zip(fsi_content.select('label'), fsi_content.select('div:has(> label) + div')):
    print('{: <160}{: <8}'.format(label.get_text(strip=True), text.get_text(strip=True)))

打印：

Label                                                                                                                                                           Value
