环境：python2.7
安装lxml模块
pip install lxml
例子：
from lxml import etree text = ‘‘‘ <div> <ul> <li class="item-0"><a href="link1.html">first item</a></li> <li class="item-1"><a href="link2.html">second item</a></li> <li class="item-inactive"><a href="link3.html">third item</a></li> <li class="item-1"><a href="link4.html">fourth item</a></li> <li class="item-0"><a href="link5.html">fifth item</a> </ul> </div> ‘‘‘ html = etree.HTML(text) #这是一个地址 result = etree.tostring(html) #读出来源码，并且补全，如输出的《body》标签 print(result)
输出：
<html> <body> <div> <ul> <li class="item-0"><a href="link1.html">first item</a></li> <li class="item-1"><a href="link2.html">second item</a></li> <li class="item-inactive"><a href="link3.html">third item</a></li> <li class="item-1"><a href="link4.html">fourth item</a></li> <li class="item-0"><a href="link5.html">fifth item</a></li> </ul> </div> </body> </html>
#读取文件里的内容 from lxml import etree html = etree.parse(‘hello.html‘) result = etree.tostring(html, pretty_print=True) print(result)
获取li标签里的东西
html = etree.parse(‘hello.html‘) print type(html) result = html.xpath(‘//li‘) print result print len(result) print type(result) print type(result[0]） |
