The DOM tree

In the DOM view, documents have a logical structure which is very much like a tree; to be more precise, which is like a ``forest'' or ``grove'', since we can work with several document trees at the same time. The DOM specification is largely organized around the Node interface, which is the basic node that trees are made of and which defines the basic methods for the traversal of the document (get the parent of a node, its first child, the next sibling and so on). More formally, the DOM tree is made of entities that implements the Node Interface.
