Example 1
from bs4 import BeautifulSoup, NavigableString
markup = '''
<div id="Languages">
<p>Java</p> <p>Python</p> <p>C++</p>
</div>
'''
soup = BeautifulSoup(markup, 'html.parser')
tag = soup.div
children = tag.children
for child in children:
print (child)Example 2
soup 对象也拥有 children 属性。
The soup object too bears the children property.
from bs4 import BeautifulSoup, NavigableString
markup = '''
<div id="Languages">
<p>Java</p> <p>Python</p> <p>C++</p>

'''
soup = BeautifulSoup(markup, 'html.parser')
children = soup.children
for child in children:
print (child)Example 3
在以下示例中，我们将 NavigableString 对象追加到 <p> 标记并获取子项列表。
In the following example, we append NavigableString objects to the <p> Tag and get the list of children.
from bs4 import BeautifulSoup, NavigableString
markup = '''
<div id="Languages">
<p>Java</p> <p>Python</p> <p>C++</p>
</div>
'''
soup = BeautifulSoup(markup, 'html.parser')
soup.p.extend(['and', 'JavaScript'])
children = soup.p.children
for child in children:
print (child)
