lxml中的解析功能出错 [英] error with parse function in lxml

问题描述

我已经在Windows平台上安装了lxml2.2.2(我使用python 2.6.5版).我尝试了以下简单命令:

i have installed lxml2.2.2 on windows platform(i m using python version 2.6.5).i tried this simple command:

from lxml.html import parse 
p= parse(‘http://www.google.com’).getroot()

但是我遇到以下错误:

Traceback (most recent call last):
File "", line 1, in p=parse(‘http://www.google.com’).getroot()
File "C:\Python26\lib\site-packages\lxml-2.2.2-py2.6-win32.egg\lxml\html_init_.py", line 661, in parse return etree.parse(filenameorurl, parser, baseurl=baseurl, **kw)

由于我是python的新手，所以我对下一步的工作一无所知.请指导我解决此错误.提前致谢！！ :)

i am clueless as to what to do next as i am a newbie to python. please guide me to solve this error. thanks in advance!! :)

推荐答案

lxml.html.parse不获取URL.

lxml.html.parse does not fetch URLs.

以下是使用urllib2的方法:

Here's how to do it with urllib2:

>>> from urllib2 import urlopen
>>> from lxml.html import parse
>>> page = urlopen('http://www.google.com')
>>> p = parse(page)
>>> p.getroot()
<Element html at 1304050>

更新
史蒂文是对的. lxml.etree.parse应该接受并加载URL.我错过了.我尝试删除此答案，但不允许这样做.

Update
Steven is right. lxml.etree.parse should accept and load URLs. I missed that. I've tried deleting this answer, but I'm not allowed.

我撤回了有关不获取URL的声明.

I retract my statement about it not fetching URLs.
