.parent

通过.parent属性来获取某个元素的父节点.在例子“爱丽丝”的文档中,<head>标签是<title>标签的父节点:

title_tag = soup.title
title_tag
# <title>The Dormouse's story</title>
title_tag.parent
# <head><title>The Dormouse's story</title></head>

文档title的字符串也有父节点:<title>标签

title_tag.string.parent
# <title>The Dormouse's story</title>

文档的顶层节点比如<html>的父节点是BeautifulSoup对象:

html_tag = soup.html
type(html_tag.parent)
# <class 'bs4.BeautifulSoup'>

BeautifulSoup对象的.parent是None:

print(soup.parent)
# None
