我怎么得到下一个标签

Question

我想知道课间的头条新闻。标题围绕着h2标签。标题在标签后面

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())

Answer 1

soup.findAll()返回一个列表（或None），因此不能对其调用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))

编辑：此脚本将从多个页面中删除标题：

import requests
from bs4 import BeautifulSoup

url = 'https://dailypost.ng/hot-news/page/{}/'

for page in range(1, 5):    # <  change how many pages do you want
    print('Page no.{}'.format(page))
    soup = BeautifulSoup(requests.get(url.format(page)).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))
    print('-' * 80)

Answer 2

必须遍历mydivs才能使用findNext（）

mydivs是web元素的列表findNext只适用于单个web元素。必须遍历div并对每个div运行findNext

加上这行就行了

for div in mydivs:

把它放在

mytags = div.findNext('h2')

以下是您的工作程序的完整代码：

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())

Answer 3

尝试将最后3行替换为：

for div in mydivs:
    mytags = div.findNext('h2')
    for tag in mytags:
        print(tag.strip())
