## org.apache.velocity.anakia
Class TreeWalker

    java.lang.Object
      org.apache.velocity.anakia.TreeWalker

public class TreeWalker
extends Object

This class allows you to walk a tree of JDOM Element objects. It first walks the tree itself starting at the Element passed into allElements() and stores each node of the tree in a Vector which allElements() returns as a result of its execution. You can then use a #foreach in Velocity to walk over the Vector and visit each Element node. However, you can achieve the same effect by calling `element.selectNodes("//*")`.
