在python中通过xpath提取A标签的值
[英]Extracting the value of A tag by xpath in python
问题描述
I have a simple python script like: 
我有一个简单的python脚本，例如：
#!/usr/bin/python
import requests
from lxml import html
response = requests.get('http://site.ir/')
out=response.content
tree = html.fromstring(open(out).read())
print [e.text_content() for e in tree.xpath('//div[class="group"]/div[class="groupinfo"]/a/text()')]
I used xpath in order to get value of tag a as you can see from image below... 我使用xpath来获取标签a值，如下图所示。 But the output sample is not what I expected.
但是输出样本不是我期望的。
UPDATE I have also the following error: 更新我也有以下错误：
Traceback (most recent call last):
File "p.py", line 7, in <module>
tree = html.fromstring(open(out).read())
IOError: [Errno 36] File name too long: '\n<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" ....

您需要将@放在属性名称的开头，以寻址XPath中的属性：
//div[@class="group"]/div[@class="groupinfo"]/a/text()
