To get all the child nodes of an element in Beautiful Soup, use the find_all() method.

Example

Consider the following HTML document:


        
        
            
                
                
                    my_html = """
       <div id="root">
             <p>Alex</p>
             <div>
                       <p>Bob</p>
                    <p>Cathy</p>
             </div>
       </div>
"""
soup = BeautifulSoup(my_html)

To get all the child nodes of the root div:


        
        
            
                
                
                    root_tag = soup.find(id="root")
root_tag.find_all(recursive=True)
                
            
            [<p>Alex</p>, <div><p>Bob</p><p>Cathy</p></div>, <p>Bob</p>, <p>Cathy</p>]

The return size of the returned list is 4 because there are 4 nodes under the root div.

As a side note, to get all immediate children:


        
        
            
                
                
                    root_tag = soup.find(id="root")
print(root_tag.find_all(recursive=False))
                
            
            [<p>Alex</p>, <div><p>Bob</p><p>Cathy</p></div>]

Notice how the size of the returned list is 2 since the root div has 2 children.
