代码如下：
#coding:UTF8
from bs4 import BeautifulSoup
html_doc = """
<html><head><title>The Dormouse's story</title></head>
<body>
<p class="title"><b>The Dormouse's story</b></p>
<p class="story">Once upon a time there were three little sisters; and their names were
<a href="http://example.com/elsie" class="sister" id="link1">Elsie</a>,
<a href="http://example.com/lacie" class="sister" id="link2">Lacie</a> and
<a href="http://example.com/tillie" class="sister" id="link3">Tillie</a>;
and they lived at the bottom of a well.</p>
<p class="story">...</p>
"""
soup=BeautifulSoup(html_doc,'html.parser',from_encoding='utf-8')
print 'hello'
links=soup.find_all('a')
for link in links:
print link.name,link['href'],link.get_text()
p_node=soup.find('p',class_="title")
print p_node.name,p_node.get_text()
错误提示：前面的url可以提取出来，后面的内容就报错
hello
a http://example.com/elsie Elsie
a http://example.com/lacie Lacie
a http://example.com/tillie Tillie
