      To extract HTML code from a web page or any HTML document, you have a few options depending on whether you want to extract it manually or programmatically:

      Manual Extraction:

      1. View Page Source:
        • Most web browsers allow you to view the HTML source of a web page:
          • Chrome: Right-click on the page and select “View Page Source” or use Ctrl+U.
          • Firefox: Right-click on the page and select “View Page Source” or use Ctrl+U.
          • Edge: Right-click on the page and select “View Source” or use Ctrl+U.
          • Safari: Enable the Develop menu in Preferences, then Develop > Show Page Source.
      2. Inspect Element (Developer Tools):
        • You can inspect specific elements on a web page using developer tools:
          • Right-click on an element and select “Inspect” or use Ctrl+Shift+I (or Cmd+Option+I on Mac) to open developer tools.
          • This allows you to view and navigate through the HTML structure of the page.
      3. Save HTML File:
        • If you want to extract the HTML of a whole web page:
          • Right-click on the page and select “Save As…” to save the entire page as an HTML file on your computer.

      Programmatic Extraction:

      If you need to programmatically extract HTML from a web page or an online resource, you can use various programming languages and tools:

      1. Using Python:
        • Use libraries like requests to fetch the HTML content and BeautifulSoup for parsing:
          python
          import requests
          from bs4 import BeautifulSoup
          url = 'https://example.com'
          response = requests.get(url)

          html_content = response.text

          soup = BeautifulSoup(html_content,

          'html.parser')
          # Now you can work with the parsed HTML content using BeautifulSoup
      2. Using JavaScript:
        • In a browser environment, you can use JavaScript to manipulate and extract HTML elements:
          javascript
          // Example to log the HTML content of the current page
          console.log(document.documentElement.outerHTML);
      3. Using Command-line Tools:
        • Tools like curl or wget combined with grep or sed can be used to fetch and extract HTML content from URLs:
          bash
          curl -s https://example.com | grep "<" # Extracts HTML tags

      Considerations:

      • Respect Permissions: Ensure you have permission to extract and use the HTML content, especially if you’re dealing with sensitive or copyrighted material.
      • Parsing: If you need to extract specific data from HTML (like text content, links, etc.), consider using parsing libraries like BeautifulSoup (Python) or regex (regular expressions) for more complex extraction tasks.
