Python之解析网页(XPath)

XPath是一门语言

练习使用XPath

html_doc = """
<div>
    <ul>
        <li class="item-0"><a href="www.baidu.com">baidu</a>
        <li class="item-1 one" name="first"><a href="https://blog.youkuaiyun.com/qq_25343557">myblog</a>
        <li class="item-1 two" name="first"><a href="https://blog.youkuaiyun.com/qq_25343557">myblog2</a>
        <li class="item-2"><a href="https://www.youkuaiyun.com/">csdn</a>
        <li class="item-3"><a href="https://hao.360.cn/?a1004">bbb</a>
        <li class="aaa"><a href="https://hao.360.cn/?a1004">aaa</a>
"""

在使用Xpath的时候需要把网页初始化

# 网页初始化
html = etree.HTML(html_doc)
# print(html)   <Element html at 0x1f8413
