# -*- coding=utf-8 -*-

from bs4 import BeautifulSoup

with open('./test.html',encoding='utf-8') as fin:
    html_doc = fin.read()

soup = BeautifulSoup(html_doc,'html.parser')

links = soup.find_all('a')
for link in links:
    print(link.name,link['href'],link.get_text())

img = soup.find('img')
print(img['src'])

# 升级版：
from bs4 import BeautifulSoup

with open('./test.html',encoding='utf-8') as fin:
    html_doc = fin.read()

soup = BeautifulSoup(html_doc,'html.parser')

div_node = soup.find('div',id = 'content') # 先查找大的区块
print(div_node)

print("#"*50)

links = div_node.find_all('a')
for link in links:
    print(link.name,link['href'],link.get_text())

img = div_node.find('img')
print(img['src'])
