How can HTML parsing be utilized to improve the efficiency of processing comments in PHP code?

When processing comments in PHP code, HTML parsing can be utilized to efficiently extract and manipulate comment data. By using an HTML parser like DOMDocument, we can easily navigate through the HTML structure and extract specific elements such as comments. This can help streamline the processing of comments in PHP code by providing a structured way to access and manipulate comment data. 

// Example PHP code snippet utilizing HTML parsing to process comments

// HTML content with comments
$html = '<!-- This is a comment --><p>Hello World</p><!-- Another comment -->';

// Create a new DOMDocument object
$dom = new DOMDocument();

// Load the HTML content into the DOMDocument
$dom->loadHTML($html);

// Get all comment nodes in the HTML content
$comments = $dom->getElementsByTagName('comment');

// Loop through each comment node and extract the comment text
foreach ($comments as $comment) {
    echo $comment->nodeValue . "\n";
}
