from tornado import httpclient
cli=tornado.httpclient.HTTPClient()
link='http://www.iciba.com/'
search=raw_input('search: ')

data=cli.fetch(link)
body=data.body.decode('utf8')

group=soup.find_all(class_='group_pos')

group2=group[0].find_all('p')
for ele in group2:
print(ele.find(class_='fl').get_text())
result=ele.find_all('label')
for r in result:
print(r.get_text())
