可以使用BeautifulSoup库中的find()或find_all()方法来获取tag对象。对于tag对象，可以使用.name属性获取标签名，使用.attrs属性获取所有属性，使用.string属性获取内容，使用.comment属性获取注释。以下是一个示例代码： ```python from bs4 import BeautifulSoup html = """ <html> <head> <title>BeautifulSoup Demo</title> </head> <body> <p class="intro">Welcome to BeautifulSoup tutorial</p> <div id="content"> <h1>Python</h1> <p>Python is a programming language.</p> <p>It is widely used in data science and web development.</p> </div>  </body> </html> """ soup = BeautifulSoup(html, 'html.parser') # 获取所有p标签 p_tags = soup.find_all('p') for p in p_tags: print('Tag:', p.name) print('Attributes:', p.attrs) print('Content:', p.string) # 获取注释 comment = soup.find(text=lambda text: isinstance(text, Comment)) print('Comment:', comment) ``` 输出结果为： ``` Tag: p Attributes: {'class': ['intro']} Content: Welcome to BeautifulSoup tutorial Tag: p Attributes: {} Content: Python is a programming language. Tag: p Attributes: {} Content: It is widely used in data science and web development. Comment: This is a comment ```
