Nodelist - 'undefined: not bound to any nodes'

What's wrong with this?

YUI().use('node', function (Y) 
{
  var doc = Y.one('#content');
  // alert(doc.getHTML());
  var nodes = new Y.NodeList(doc.getElementsByTagName('h1'));
  // Do something ...
});

doc.getHTML() shows the expected document with some level 1 headings. But nodes is always 'undefined: not bound to any nodes'.

Thx for your help!

'doc' is a Y.Node object, not a native DOM object, and so does not have a getElementsByTagName() method. In this case, I think you want:

var nodes = doc.all('h1');

Keep in mind that when manipulating the DOM with YUI, you are working with a facade object, a Y.Node or a Y.NodeList. Don't mix YUI method calls with native DOM method calls unless you are sure you know what you are doing.
