What are the advantages and disadvantages of using DOMDocument in PHP to parse HTML tables compared to other methods?

When parsing HTML tables in PHP, using the DOMDocument class provides a more structured and reliable way to extract data compared to other methods like regular expressions. DOMDocument allows you to navigate the HTML document tree easily and access specific elements such as tables and their rows and cells. However, using DOMDocument can be more resource-intensive and may require more code compared to simpler methods. 

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

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

// Get all table elements in the HTML
$tables = $doc->getElementsByTagName('table');

// Loop through each table
foreach ($tables as $table) {
    // Process each table, rows, and cells here
}
