What are some alternative methods, besides regular expressions, for extracting specific content from a webpage using PHP?

When extracting specific content from a webpage using PHP, besides regular expressions, another method is to use PHP DOMDocument and DOMXPath. This allows for easier navigation and manipulation of the HTML structure of the webpage. By using DOMDocument to load the webpage and DOMXPath to query specific elements, you can extract the desired content more efficiently. 

<?php
// Load the webpage content
$html = file_get_contents('https://www.example.com');

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

// Create a new DOMXPath
$xpath = new DOMXPath($dom);

// Query specific elements using XPath
$elements = $xpath->query('//div[@class="content"]');

// Loop through the elements and extract content
foreach ($elements as $element) {
    echo $element->textContent;
}
?>
