Document.documentElement returns the Element that is the root element of the document (for example, the <html> element for HTML documents).
Syntax
var element = document.documentElement;
Example
var rootElement = document.documentElement;
var firstTier = rootElement.childNodes;
// firstTier is the NodeList of the direct children of the root element
for (var i = 0; i < firstTier.length; i++) {
// do something with each direct kid of the root element
// as firstTier[i]
}
Notes
For any non-empty HTML document, document.documentElement will always be an <html> element. For any non-empty XML document, document.documentElement will always be whatever element is the root element of the document.
