我已经使用easy_install安装了BeautifulSoup并尝试运行以下脚本

from BeautifulSoup import BeautifulSoup
import re

doc = ['<html><head><title>Page title</title></head>',
       '<body><p id="firstpara" align="center">This is paragraph <b>one</b>.',
       '<p id="secondpara" align="blah">This is paragraph <b>two</b>.',
       '</html>']
soup = BeautifulSoup(''.join(doc))

print soup.prettify()

但不确定为什么会这样

Traceback (most recent call last):
  File "C:\Python27\reading and writing xml file from web1.py", line 49, in <module>
    from BeautifulSoup import BeautifulSoup
ImportError: No module named BeautifulSoup

能否请你帮忙.谢谢
