python Beautifulsoup：获取script脚本标签和内容-马育民老师

# 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>

'''

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>

'''

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>

'''

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')
```
