如何确定html的这些元素? [英] How to determine these elements of html?

问题描述

在此答案中，@ Andrej Kesely使用以下代码从

In this answer, @Andrej Kesely use the following code to remove unnecessary elements (ads, huge space,...) from html of this url.

import requests
from bs4 import BeautifulSoup

url = 'https://www.collinsdictionary.com/dictionary/french-english/aimer'
headers = {'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0'}
soup = BeautifulSoup(requests.get(url, headers=headers).content, 'html.parser')

for script in soup.select('script, .hcdcrt, #ad_contentslot_1, #ad_contentslot_2'):
    script.extract()

print(soup.h2.text)
print(''.join(map(str, soup.select_one('.hom').contents)))

在我看来，那些不必要的元素用script, .hcdcrt, #ad_contentslot_1, #ad_contentslot_2标记.

It seems to me that those unnecessary elements are marked by script, .hcdcrt, #ad_contentslot_1, #ad_contentslot_2.
