Class w3c.xmlOnline.xptr.Xptr 

java.lang.Object
   |
   +----w3c.xmlOnline.xptr.Xptr
public class Xptr
extends Object
A class that implements TEI XPTR's. Create an instance of this class with Xptr("ROOT,CHILD(1)(ALL,*,DIR,*)") or any Xpointer string, than apply it to a node in an XML tree, with apply(node). The return value is an array of nodes that satisfy the query.

The current algorithms are not very efficient. Some work remains to be done here.
