What are some best practices for extracting specific data from HTML tags in PHP to avoid errors and ensure accurate results?

When extracting specific data from HTML tags in PHP, it's important to use a reliable parsing library like DOMDocument to avoid errors and ensure accurate results. By using DOMDocument, you can easily navigate through the HTML structure and extract the desired data without worrying about malformed HTML or missing tags. 

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

// Load the HTML content from a file or string
$doc->loadHTML($html);

// Use DOMXPath to query specific elements based on XPath expressions
$xpath = new DOMXPath($doc);
$elements = $xpath->query('//div[@class="content"]');

// Loop through the matched elements and extract the data
foreach ($elements as $element) {
    $specificData = $element->textContent;
    // Do something with the extracted data
}
