    import urllib2,re
    import sys
    def getHtml(url,time=10):
     response = urllib2.urlopen(url,timeout=time)
     html = response.read()
     response.close()
     return html
    def clearBlank(html):
     if len(html) == 0 : return ''
     html = re.sub('\r|\n|\t','',html)
     while html.find(" ")!=-1 or html.find(' ')!=-1 :
      html = html.replace(' ',' ').replace(' ',' ')
     return html
    if __name__ == '__main__':

      html = html.decode('gb2312','replace').encode('utf-8') #转码
      title_reg = r'<h1 class="title" id="[\d]+">(.*?)</h1>'
      content_reg = r'<div class="card-summary-content">(.*?)</p>'
      title = re.compile(title_reg).findall(html)
      content = re.compile(content_reg).findall(html)
      title[0] = re.sub(r'<[^>]*?>', '', title[0])
      content[0] = re.sub(r'<[^>]*?>', '', content[0])
      print title[0]
      print '#######################'
      print content[0]
