What are the advantages of using regular expressions in PHP for parsing HTML elements compared to DOM manipulation?

When parsing HTML elements in PHP, using regular expressions can offer more flexibility and control compared to DOM manipulation. Regular expressions allow for precise pattern matching, making it easier to extract specific elements or attributes from HTML content. Additionally, regular expressions can be more efficient for simple parsing tasks where full DOM manipulation might be overkill. 

$html = file_get_contents('example.html');

// Using regular expressions to extract all <a> tags and their href attributes
preg_match_all('/<a\s[^>]*href="([^"]*)"/i', $html, $matches);

// Outputting the matched <a> tags and href attributes
foreach ($matches[0] as $key => $match) {
    echo "Link: " . $match . "\n";
    echo "Href: " . $matches[1][$key] . "\n";
}
