如何得到下一个标签？
如何得到下一个标签？
提问于 2019-12-31 20:27:09
我正试图得到介于班级之间的头条新闻。标题围绕着h2标签。标题出现在标签后面。
from bs4 import BeautifulSoup
import requests
r = requests.get("https://www.dailypost.ng/hot-news")
soup = BeautifulSoup(r.content, "html.parser")
mydivs = soup.findAll("span", {"class": "mvp-cd-date left relative"})
mytags = mydivs.findNext('h2')
for tag in mytags:
print(tag.text.strip())回答 3

您必须遍历mydivs 才能使用findNext()
mydivs是一个web元素列表。findNext只适用于单个web元素。您必须遍历div并对每个div运行findNext。
只需加上这一行
for div in mydivs:把它放在前面
mytags = div.findNext('h2')以下是您的工作计划的完整代码：
from bs4 import BeautifulSoup
import requests
r = requests.get("https://www.dailypost.ng/hot-news")
soup = BeautifulSoup(r.content, "html.parser")
mydivs = soup.findAll("span", {"class": "mvp-cd-date left relative"})
for div in mydivs:
mytags = div.findNext('h2')
for tag in mytags:
print(tag.strip())Stack Overflow用户

soup.findAll()返回一个列表(或None)，因此不能在其上调用findNext()。但是，您可以迭代标记并分别调用每个标记上的find_next()：
import requests
from bs4 import BeautifulSoup
r = requests.get("https://www.dailypost.ng/hot-news")
soup = BeautifulSoup(r.content, "html.parser")
mydivs = soup.findAll("span", {"class": "mvp-cd-date left relative"})
for tag in mydivs:
print(tag.find_next('h2').get_text(strip=True))指纹：

尝试将最后3行替换为：
for div in mydivs:
mytags = div.findNext('h2')
for tag in mytags:
