python的lxml模塊
阿新 • • 發佈：2017-10-27
python lxml
環境：python2.7
安裝lxml模塊
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) #這是一個地址
result = etree.tostring(html) #讀出來源碼，並且補全，如輸出的《body》標簽
print(result)輸出：
<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>#讀取文件裏的內容 from lxml import etree html = etree.parse(‘hello.html‘) result = etree.tostring(html, pretty_print=True) print(result)
獲取li標簽裏的東西
html = etree.parse(‘hello.html‘) print type(html) result = html.xpath(‘//li‘) print result print len(result) print type(result) print type(result[0]） |
