如下所示：
from bs4 import BeautifulSoup
path = './web/new_index.html'
with open(path, 'r') as f:
Soup = BeautifulSoup(f.read(), 'lxml')
titles = Soup.select('ul > li > div.article-info > h3 > a')
for title in titles:
print(title.text)
输出：
Sardinia's top 10 beaches
How to get tanned
How to be an Aussie beach bum
Summer's cheat sheet
#其中
titles = Soup.select('ul > li > div.article-info > h3 > a')
#等效
titles = Soup.select('h3 a')
print(title.text) #等效 print(title.get_text()) print(title.string)
也可以使用以下代码
import bs4
path = './web/new_index.html'
with open(path, 'r') as f:
Soup = bs4.BeautifulSoup(f.read(), 'lxml')
titles = Soup.select('h3 a')
for title in titles:
print(title.string)
