使用lxml和python浏览谷歌新闻

我正在尝试使用python和lxml抓取Google新闻。一切都进行得很顺利，但当我试图使用for循环打印每个div数据时，一切都搞砸了。 这是我的代码：

# -*- coding: utf-8 -*-

from stem import Signal
from stem.control import Controller
from lxml import html
from lxml import cssselect
from lxml import etree
import requests

proxies = {
    'http' : 'http://127.0.0.1:8123'
}

headers = {
    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36'
}

url = "https://www.google.it/search?hl=en&tbm=nws&as_occt=any&tbs=cdr:1,cd_min:9/1/2014,cd_max:9/1/2014,sbd:1&as_nsrc=Daily%20Mail&start=0"

page = requests.get(url,proxies=proxies,headers=headers)
tree = html.fromstring(page.content)
results = tree.xpath('//div[@class="_cnc"]')

for div in results:
    print(div)

我得到这个输出：

<Element div at 0x7f4154df9470>
<Element div at 0x7f4154df94c8>
<Element div at 0x7f4154df9520>
<Element div at 0x7f4154df9578>
<Element div at 0x7f4154df95d0>
<Element div at 0x7f4154df9628>
<Element div at 0x7f4154df9680>
<Element div at 0x7f4154df96d8>
<Element div at 0x7f4154df9730>
<Element div at 0x7f4154df9788>

当我尝试打印时，我得到相同的多重输出：

有人知道我的代码出了什么问题吗？

你几乎做到了-只需在内部XPath表达式前面加上点，使它们特定于当前节点的上下文：

for div in results:
    title = div.xpath('.//a[@class="l _HId"]/text()')
    href = div.xpath('.//a[@class="l _HId"]/@href')
    snippet = div.xpath('.//div[@class="st"]/text()')
    #for example
    print(title)

for div in results:
    title = div.xpath('.//a[@class="l _HId"]/text()')
    href = div.xpath('.//a[@class="l _HId"]/@href')
    snippet = div.xpath('.//div[@class="st"]/text()')
    #for example
    print(title)
