Python 抓取html所有特定元素的方法

直接上代码哦，够直接了吧~

from lxml import etree
#import mechanize
import lxml.html
#import cookielib

#br = mechanize.Browser()
#r = br.open('http://yourdomain.com')
#html = br.response().read()
#root = lxml.html.fromstring(html)
#divs = root.xpath("//div[@class='test']")
hparser = etree.HTMLParser(encoding='utf-8') #for avoiding unicode codec problems
htree = etree.parse('http://yourdomain.com',hparser)
htree.write('/tmp/bi.html') 
divs= htree.xpath("//div[@class='test']")

要获取class包含test的所有div，比如<div class="test website"></div>

把上述xpath的参数修改为 "div[contains(@class,'test')]" 即可。
