Adding #document nodes as children

I am using node and xmldom. On ocasion I parse XML from a string with the intention of adding it as a child to another element. However, I am confused by the following code:

var dom = require('xmldom').DOMParser;
var s   = require('xmldom').DOMSerializer;

var childToBe = new dom().parseFromString('<div id="foo">Text</div>');
var parent = nodeWhereIWantToInsertChild();

parent.appendChild(childToBe);

This works just fine, and when I serialize it, I get what I expected

<parent><div id="foo">Text</div></parent>

Therefore, since div is the child of parent, 

parent.childNodes[0].nodeName == 'div' // is true as expected.

Then why is 

childToBe.nodeName == '#document' // ->True ????
childToBe.getAttribute('id') // ->Error, no method 'getAttribute'

If childToBe is a #document and I appended it to parent, why doesn't parent have a #document child?

Thanks!!

parseFromString returns a Document instance, not an Element instance. Your appendChild call should probably be throwing an exception since Document is not allowed as a child of Element, but the Node parser implementation probably doesn't bother checking.

What you probably want is to get the root element of the document:

var doc = new dom().parseFromString('<div id="foo">Text</div>');
var childToBe = doc.documentElement;
