XML DOM - The Document Object
The Document object represents the entire XML document.
The Document object
The Document object is the root of a document tree, and gives us the primary
access to the document's data.
Since element nodes, text nodes, comments, processing instructions, etc.
cannot exist outside the document, the Document object also contains methods to
create these objects. The Node objects have a ownerDocument property which
associates them with the Document where they were created.
