The Document interface represents the entire HTML or XML document.
Conceptually, it is the root of the document tree, and provides the
primary access to the document's data.
Since elements, text nodes, comments, processing instructions,
etc. cannot exist outside the context of a Document, the Document
interface also contains the factory methods needed to create these
objects. The Node objects created have a ownerDocument attribute
which associates them with the Document within whose context they
were created.
The DocumentImpl class also implements the DOM Level 2 DocumentTraversal
interface. This interface is comprised of factory methods needed to
create NodeIterators and TreeWalkers. The process of creating NodeIterator
objects also adds these references to this document.
After finishing with an iterator it is important to remove the object
using the remove methods in this implementation. This allows the release of
the references from the iterator objects to the DOM Nodes.
Note: When any node in the document is serialized, the
entire document is serialized along with it.
