Question

我想根据前面的标记选择元素的内容：

<h4>Models &amp; Products</h4>
    <div class="profile-area">...</div>

<h4>Production Capacity (year)</h4>
    <div class="profile-area">...</div>

如何获得＆＃34;个人资料区＆＃34;基于前一个标签内容的值？

这是我的代码：

import requests
from bs4 import BeautifulSoup
import csv
import re

html_doc = """
<html>
<body>
  <div class="col-md-6">
    <iframe class="factory_detail_google_map" frameborder="0" src=
    "https://www.google.com/maps/embed/v1/search?q=3.037787%2C101.38189&amp;key=AIzaSyCMDADp9QHYbQ8OBGl8puAOv-16W8ziz7Y"
    allowfullscreen=""></iframe>
  </div>

  <div class="col-md-12">
    <h4>Models &amp; Products</h4>

    <div class="profile-area">
      Large Buses, Trucks, Trailer-heads
    </div>

    <h4>Production Capacity (year)</h4>

    <div class="profile-area">
      Vehicle 700 units /year
    </div>

    <h4>Output</h4>

    <div class="profile-area">
      Vehicle 356 units ( 2016 )
    </div>

    <div class="profile-area">
      Vehicle 477 units ( 2015 )
    </div>

    <div class="profile-area">
      Vehicle 760 units ( 2014 )
    </div>

    <div class="profile-area">
      Vehicle 647 units ( 2013 )
    </div>
  </div>
</body>
</html>
"""
soup = BeautifulSoup(html, 'lxml')

#link=soup.iframe.get('src')
#print(link.split("%2C"))

for item in soup.select("div.profile-area"):
    print(item.text)

正如您所看到的，我也尝试将Google地图链接拆分为坐标，但我可能会自行解决。

感谢您的帮助！

使用.find_previous_sibling()显式查找前一个h4标记：

for item in soup.select("div.profile-area"):
    prev_h4 = item.find_previous_sibling('h4').text
    if 'Capacity' in prev_h4:
        print(item.text)

<强>输出

Vehicle 700 units /year

BeautifulSoup：根据前一个标签的内容打印div
