from bs4 import BeautifulSoup as bs
from lxml import etree
import requests
content=requests.get('http://www.ccgp.gov.cn/cggg/dfgg/zbgg/201612/t20161214_7737637.htm').text.decode('utf-8')
x=etree.HTML(content)
print x.xpath('//p[@class ="vT_detail_content w760c"]/b/p[3]/table/tbody/tr[4]/td[2]/p/span')#返回空
content=bs(content,'lxml')
r=content.select('.vT_detail_content table tr')[5].select('td')[1].select('p span')
print(r[0].string)
