DOM tugunlarini nusxalash
Tugunni nusxalash
cloneNode() metodi ko‘rsatilgan tugunning nusxasini yaratadi.
cloneNode() metodi bitta parametrga (true yoki false) ega. Bu parametr nusxalangan tugun asl tugunning barcha atributlari va bola tugunlarini o‘z ichiga olishi kerakmi yoki yo‘qligini bildiradi.

oldNode = xmlDoc.getElementsByTagName('book')[0];
newNode = oldNode.cloneNode(true);
xmlDoc.documentElement.appendChild(newNode);
