DOMNode to DOMElement in php

Question

I want to convert a DOMNode object from a call to getElementsByTagName() to a DOMElement in order to access methods like getElements

Answer 1

This is what I use in my project to minimize IDE warning.

/**
 * Cast a DOMNode into a DOMElement
 */
    function cast_e(DOMNode $node) : DOMElement {
    if ($node) {
        if ($node->nodeType === XML_ELEMENT_NODE) {
            return $node;
        }
    }
    return null;
}
