请问P段落怎么提取不出文字？

# coding:utf8

from bs4 import BeautifulSoup

import re

html_doc = """

<html><head><title>The Dormouse's story</title></head>

<body>

The Dormouse's 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.

...

"""

soup = BeautifulSoup(html_doc,'html.parser',from_encoding='utf-8')

print'获取所有连接'

links = soup.find_all('a')

for link in links:

print link.name,link['href'],link.get_text()

print'获取lacie的连接'

link_node=soup.find('a',href='http://example.com/lacie')

print link_node.name,link_node['href'],link_node.get_text()

print'正则匹配'

link_node=soup.find('a',href=re.compile(r"ill"))

print link_node.name,link_node['href'],link_node.get_text()

print'p段落文字'

p_node=soup.find('a',class_="title")

print p_node.name, p_node.get_text()

会报错如下

获取所有连接

a http://example.com/elsie Elsie

a http://example.com/lacie Lacie

a http://example.com/tillie Tillie

获取lacie的连接

a http://example.com/lacie Lacie

正则匹配

a http://example.com/tillie Tillie

p段落文字

Traceback (most recent call last):

File "C:\Users\Administrator\workspace\2.7\66\test_bs4.py", line 34, in <module>

print p_node.name, p_node.get_text()

AttributeError: 'NoneType' object has no attribute 'name'
