Example 1

我们将在本示例中使用以下 HTML 脚本：

We shall use following HTML script in this example −

<html>
   <body>
      <h2>Departmentwise Employees</h2>
      <ul id="dept">
      <li>Accounts</li>
      <ul id='acc'>
      <li>Anand</li>
      <li>Mahesh</li>
      </ul>
      <li>HR</li>
      <ol id="HR">
      <li>Rani</li>
      <li>Ankita</li>
      </ol>
      </ul>
   </body>
</html>

在以下示例中，我们找到包含字符串“HR”的标记的名称。

In the following example, we find the name of the tag that is parent to the string 'HR'.

from bs4 import BeautifulSoup

soup = BeautifulSoup(html, 'html.parser')
obj=soup.find(string='HR')
print (obj.find_parent().name)

Output

li

Example 2

<body> 标记始终包含在顶级 <html> 标记中。在以下示例中，我们使用 find_parent() 方法来确认这一事实 -

The <body> tag is always enclosed within the top level <html> tag. In the following example, we confirm this fact with find_parent() method −

from bs4 import BeautifulSoup

soup = BeautifulSoup(html, 'html.parser')
obj=soup.find('body')
print (obj.find_parent().name)

Output

html
