The ContainerNode trait

Introduction

Allows the extended PHP DOM classes to simulate inheriting from a theoretical extended \DOMNode. This one implements improved DOM child insertion methods.

trait MensBeam\HTML\ContainerNode {

    use Node;

    public appendChild ( \DOMNode $node ) : \DOMNode|false
    public insertBefore ( \DOMNode $node , \DOMNode|null $child = null ) : \DOMNode|false

}
