如何从 Beautifulsoup 中删除结果的 HTML 标签 find all

Question

我需要使用 python 和 beautifulsoup.

删除标签并仅保留以下代码输出中的文本

输出：

import requests
from bs4 import BeautifulSoup as bs
r = requests.get("https://www.w3schools.com/html/html_intro.asp")
soup = bs(r.content)
print(soup.prettify())


first_header = soup.find(["h2", "h2"])

first_headers = soup.find_all(["h2", "h2"])
first_headers

Answer 1

要仅从 ResultSet 中获取文本，请对其进行迭代，例如使用 list comprehension，为每个元素调用 .text，并通过 whitespace:

为所有文本元素调用 .join()

' '.join([e.text for e in soup.find_all('h2')])  

例子

import requests
from bs4 import BeautifulSoup as bs
r = requests.get("https://www.w3schools.com/html/html_intro.asp")
soup = bs(r.content)


first_headers = ' '.join([e.text for e in soup.find_all('h2')])

print(first_headers)

输出

Answer 2

import requests
from bs4 import BeautifulSoup as bs
r = requests.get("https://www.w3schools.com/html/html_intro.asp")
soup = bs(r.content,features="html.parser") # getting content from webpage
# retriving all h1 and h2 tags and extracting text from each of them 
first_headers = [html.text for html in soup.find_all(["h1", "h2"])] 
print(first_headers)

我使用列表理解在一行中解决了它，你可以使用 for 循环来代替

import requests
from bs4 import BeautifulSoup as bs
r = requests.get("https://www.w3schools.com/html/html_intro.asp")
soup = bs(r.content,features="html.parser")

first_headers = soup.find_all(["h1", "h2"])
for i in first_headers:
    print(i.text)

这是我的代码的输出：
