python的lxml模块
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]） |
