What are the best practices for efficiently parsing and processing HTML content in PHP using libraries like Simple HTML DOM?

When parsing and processing HTML content in PHP using libraries like Simple HTML DOM, it is important to follow best practices to ensure efficiency. One key practice is to minimize the number of DOM queries by storing the parsed HTML in a variable and accessing elements within that variable. Additionally, using CSS selectors to target specific elements can help streamline the parsing process. Finally, it is recommended to properly handle errors and exceptions to prevent any issues during parsing. 

// Include the Simple HTML DOM library
include('simple_html_dom.php');

// Load the HTML content from a URL
$html = file_get_html('http://example.com');

// Check if the HTML content was loaded successfully
if($html){
    // Find and extract specific elements using CSS selectors
    $title = $html->find('title', 0)->plaintext;
    $paragraphs = $html->find('p');

    // Process the extracted elements
    echo "Title: " . $title . "<br>";
    foreach($paragraphs as $paragraph){
        echo "Paragraph: " . $paragraph->plaintext . "<br>";
    }
} else {
    echo "Error loading HTML content.";
}
