参照bs4官方中文文档 http://beautifulsoup.readthedocs.org/en/latest/ 照着写了个简单的例子，感觉它非常强大！！
import urllib.request
from bs4 import BeautifulSoup
import sys
url = 'http://www.tantengvip.com'
html = urllib.request.urlopen(url).read()
soup = BeautifulSoup(html)
h1s = soup.find_all('h1',class_='entry-title')
'''打印所有H1标题和链接'''
for h1 in h1s:
#print(h1)
print(h1.get_text())
print(h1.a.attrs['href'])
结果：
D:\learn-python>python test.py

刚开始听说bs好就用bs 后来用了xpath后就几乎不太用bs了 随后知道lxml性能也比bs强后就彻底不用bs了。
