org.custommonkey.xmlunit.XpathNodeTracker

All Implemented Interfaces:

XMLConstants

public class XpathNodeTracker
extends java.lang.Object
implements XMLConstants

Tracks Nodes visited by the DifferenceEngine and converts that information into an Xpath-String to supply to the NodeDetail of a Difference instance
