What common mistakes should be avoided when working with DOMDocument and DOMXPath in PHP?

One common mistake to avoid when working with DOMDocument and DOMXPath in PHP is not checking if the document loaded successfully before performing operations. This can lead to errors if the document fails to load properly. To solve this, always check if the document loaded successfully before proceeding with any operations. 

$doc = new DOMDocument();
if($doc->loadHTML($html)){
    $xpath = new DOMXPath($doc);
    // Perform operations with DOMXPath here
} else {
    echo "Failed to load HTML document";
}
