5. var children = nd.childNodes; for (var i = 0; i < children.length; i++) { alert(children[i].nodeType); } divs = document.getElementsByTagName('div'); for (var i = 0; i < divs.length; i++) { alert(divs[i].id); } var elem = document.getElementById("elem1"); var children = elem.childNodes; var child = elem.getElementsByTagName('h1')[0]; var p = document.createElement("p"); var txt = document.createTextNode("hello"); p.appendChild(txt); elem.replaceChild(p,child);

6. The solution is:

7. divs = document.getElementsByTagName('div'); for (var i = 0; i < divs.length; i++) { alert(divs[i].id); }

8. The solution is:

9. var elem = document.getElementById("elem1"); var children = elem.childNodes; var child = elem.getElementsByTagName('h1')[0]; var p = document.createElement("p"); var txt = document.createTextNode("hello"); p.appendChild(txt); elem.replaceChild(p,child);
