Interface ElementTraversal


public interface ElementTraversal
The ElementTraversal interface is a set of read-only attributes which allow an author to easily navigate between elements in a document.

In conforming implementations of Element Traversal, all objects that implement Element must also implement the ElementTraversal interface. Four of the methods, getFirstElementChild(), getLastElementChild(), getPreviousElementSibling(), and getNextElementSibling(), each provides a live reference to another element with the defined relationship to the current element, if the related element exists. The fifth method, getChildElementCount(), exposes the number of child elements of an element, for preprocessing before navigation.
