Extract content of <script> with BeautifulSoup

Extract content of <script> with BeautifulSoup

To extract the content within <script> tags using BeautifulSoup, you can navigate the parsed HTML document and access the tag's string attribute. Here's how you can achieve this:

from bs4 import BeautifulSoup # Example HTML content html_content = """ <html> <head> <title>Sample Page</title> </head> <body> <p>This is some content.</p> <script> var a = 10; var b = 20; console.log(a + b); </script> <p>More content here.</p> </body> </html> """ # Parse the HTML content soup = BeautifulSoup(html_content, 'html.parser') # Find all <script> tags script_tags = soup.find_all('script') # Extract content within <script> tags script_contents = [script.string for script in script_tags if script.string is not None] # Print extracted script contents for content in script_contents: print(content)

In this example, the find_all('script') method is used to find all <script> tags in the HTML document. Then, the content within each <script> tag is extracted using the string attribute. The code iterates over each script content and prints it.

Keep in mind that the string attribute returns the text content of the tag as a string, including any whitespace and line breaks. If you want to further process the JavaScript code, you can manipulate the extracted strings as needed.
