Python读取本地文件并解析网页元素的方法

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)
