获取所有脚本标签
要获取所有脚本标签，我们需要使用 find_all() 函数
from bs4 import BeautifulSoup # Import BeautifulSoup module
html = '''
<head>
<script src="/static/js/prism.js"></script>
<script src="/static/js/bootstrap.bundle.min.js"></script>
<script src="/static/js/main.js"></script>
<script> console.log('Hellow BeautifulSoup') </script>
</head>
'''
soup = BeautifulSoup(html, 'html.parser')
scripts = soup.find_all("script")
for script in scripts:
print(script)
输出：
<script src="/static/js/prism.js"></script>
<script src="/static/js/bootstrap.bundle.min.js"></script>
<script src="/static/js/main.js"></script>
<script> console.log('Hellow BeautifulSoup') </script>
获取脚本文件附带的脚本标签
获取 <script> 标签的 src 属性值，需要：
- 使用
find_all()函数 - 设置
src=True参数
html = '''
<head>
<script src="/static/js/prism.js"></script>
<script src="/static/js/bootstrap.bundle.min.js"></script>
<script src="/static/js/main.js"></script>
<script> console.log('Hellow BeautifulSoup') </script>
</head>
'''
soup = BeautifulSoup(html, 'html.parser') # ?️ Parsing
scripts = soup.find_all("script", src=True) # ?️ Find all script tags that come with the src attribute
for script in scripts:
print(script['src'])
输出：
/static/js/prism.js
/static/js/bootstrap.bundle.min.js
/static/js/main.js
获取脚本标签的内容
要获取脚本标签的内容，需要使用 .string 属性。但是，让我们看一个例子：
html = '''
<head>
<script src="/static/js/prism.js"></script>
<script src="/static/js/bootstrap.bundle.min.js"></script>
<script src="/static/js/main.js"></script>
<script> console.log('Hellow BeautifulSoup') </script>
</head>
'''
soup = BeautifulSoup(html, 'html.parser') # ?️ Parsing
scripts = soup.find_all("script", string=True) # ?️ Find all script tags
print(scripts) # ?️ Print Result
for script in scripts: # ?️ Loop Over scripts
print(script.string)
输出：
[<script> console.log('Hellow BeautifulSoup') </script>]
console.log('Hellow BeautifulSoup')
