Example


<!DOCTYPE html>
<html lang = "en">
<head>
    <meta charset = "UTF-8">
    <title> Sample Page </title>
</head>
<body>
    <h1> Welcome to My Website </h1>
    <p> This is a sample paragraph. </p>
    <ul>
        <li> Item 1 </li>
        <li> Item 2 </li>
    </ul>
</body>
</html>

2. Utilizing Web Scraping Libraries:

Utilizing libraries such as BeautifulSoup in Python or Scrapy can enhance the process of extracting HTML content. These tools are designed to parse HTML documents efficiently, automatically focusing on the most relevant text content and providing users with greater control over the extraction process.

Example


from bs4 import BeautifulSoup

# HTML Content
html_content = """
<!DOCTYPE html>
<html lang = "en">
<head>
    <meta charset = "UTF-8">
    <title> Sample Page </title>
</head>
<body>
    <h1> Welcome to My Website </h1>
    <p> This is a sample paragraph. </p>
    <ul>
        <li> Item 1 </li>
        <li> Item 2 </li>
    </ul>
</body>
</html>
"""

# Parse HTML and extract text
soup = BeautifulSoup( html_content, ' html.parser ' )
text_content = soup.get_text()

print( text_content )
