How to get reference to DocumentTraversal |
|
|
Since Level 2 DOM has a set of tools allowing convenient navigation thrgough
the DOM-tree. New package org.w3c.dom.traversal contained a mean for filtering
the nodes by a bit mask, linear iterating and walking through a tree.
The entry-point there is interface DocumentTraversal. There is no explicit way
like getter method in DOM to get instance of DocumentTraversal. But most
implementations implies that DOM-document realization also implementats this
interface.
Thus, the following example shows how to get traversal tool from DOM-document:
// first you get a document somewhere: create or load from a file:
Document document = loader....;
// ...
// then you can simply cast you document instance to traversal:
DocumentTraversal traversal = (DocumentTraversal) document;
