在BeautifulSoup中删除以前的同级元素,可以使用extract()方法。该方法可以将指定的元素从文档树中移除,并返回被移除的元素。
具体步骤如下:
from bs4 import BeautifulSoup
html = '''
<html>
<body>
<div class="container">
<h1>Title</h1>
<p>Paragraph 1</p>
<p>Paragraph 2</p>
<p>Paragraph 3</p>
</div>
</body>
</html>
'''
soup = BeautifulSoup(html, 'html.parser')
<p>
标签,可以使用以下代码:container = soup.find('div', class_='container')
paragraphs = container.find_all('p')
for p in paragraphs:
p.extract()
print(soup.prettify())
完整的代码示例:
from bs4 import BeautifulSoup
html = '''
<html>
<body>
<div class="container">
<h1>Title</h1>
<p>Paragraph 1</p>
<p>Paragraph 2</p>
<p>Paragraph 3</p>
</div>
</body>
</html>
'''
soup = BeautifulSoup(html, 'html.parser')
container = soup.find('div', class_='container')
paragraphs = container.find_all('p')
for p in paragraphs:
p.extract()
print(soup.prettify())
