本文介绍如何使用Python的BeautifulSoup库解析HTML文档，并通过实例展示了如何获取HTML文档中各元素的内容。具体演示了.contents属性的应用，它能将HTML文档中的换行符也作为子节点的一部分。

BeautifulSoup的文档见 https://www.crummy.com/software/BeautifulSoup/bs4/doc.zh/

其中.contents 会将换行也记录为一个子节点

from bs4 import BeautifulSoup

html_doc = """
<html><head><title>The Dormouse's story</title></head>
<body>
<p class="title"><b>The Dormouse's story</b></p>
<p class="story">Once upon a time there were three little sisters; and their names were
<a href="http://example.com/elsie" class="sister" id="link1">Elsie</a>,
<a href="http://example.com/lacie" class="sister" id="link2">Lacie</a> and
<a href="http://example.com/tillie" class="sister" id="link3">Tillie</a>;
and they lived at the bottom of a well.</p>
<p class="story">...</p>
"""
soup = BeautifulSoup(html_doc, "lxml")
print( (soup.body.contents) )

输出：

['\n', The Dormouse's story, '\n', Once upon a time there were three little sisters; and their names were
<a class="sister" href="http://example.com/elsie" id="link1">Elsie</a>,
<a class="sister" href="http://example.com/lacie" id="link2">Lacie</a> and
<a class="sister" href="http://example.com/tillie" id="link3">Tillie</a>;
and they lived at the bottom of a well., '\n', ..., '\n']

共7个元素
