What are the potential pitfalls of using the PHP DOM method for web scraping?

Potential pitfalls of using the PHP DOM method for web scraping include the complexity of navigating the DOM structure, the need for handling errors and exceptions, and the performance impact of parsing large documents. To mitigate these issues, it is recommended to use a library like Simple HTML DOM Parser, which provides a simpler interface for extracting data from HTML documents. 

// Use Simple HTML DOM Parser library for easier web scraping
include('simple_html_dom.php');

// Create a new instance of Simple HTML DOM Parser
$html = file_get_html('http://example.com');

// Find elements by tag name
$elements = $html->find('a');

// Loop through elements and extract data
foreach($elements as $element) {
    echo $element->plaintext . '<br>';
}
