Examples
Before publishing a blog snippet
Input: <p>Hello <script>alert(1)</script><a href='https://example.com'>link</a></p>
Output: <p>Hello <a href="https://example.com">link</a></p>
Scripts are removed while safe content remains.
Reviewing user-generated content
Input: <img src='photo.jpg' onerror='alert(1)'><strong>Nice post</strong>
Output: <img src="photo.jpg"><strong>Nice post</strong>
Dangerous event handlers are stripped from elements.
