Are there best practices for maintaining the structure of HTML elements when using htmlpurifier in PHP?

When using htmlpurifier in PHP, it is important to maintain the structure of HTML elements to prevent any potential security vulnerabilities or unexpected output. To ensure the structure is preserved, you can configure htmlpurifier to allow specific elements and attributes while filtering out any potentially harmful content. 

// Example code snippet to configure htmlpurifier to maintain HTML structure
require_once '/path/to/HTMLPurifier.auto.php';

$config = HTMLPurifier_Config::createDefault();
$config->set('HTML.Allowed', 'p,b,a[href],img[src|alt]');

$purifier = new HTMLPurifier($config);

$dirty_html = '<p><b>Hello</b> <a href="example.com">World</a></p>';
$clean_html = $purifier->purify($dirty_html);

echo $clean_html;
