How can PHP developers address the issue of regular expressions not capturing specific text patterns within HTML content?

Regular expressions may struggle to capture specific text patterns within HTML content due to the complexity of HTML structure. One way to address this issue is by using a DOM parser like PHP's DOMDocument to parse the HTML content and extract the specific text patterns. This approach allows for more accurate and reliable extraction of text from HTML content. 

$html = '<div><p>This is some <strong>sample</strong> HTML content.</p></div>';

$dom = new DOMDocument();
$dom->loadHTML($html);

$xpath = new DOMXPath($dom);
$elements = $xpath->query('//p/strong');

foreach ($elements as $element) {
    echo $element->nodeValue; // Output: sample
}
