Class DomTripNavigator

  • All Implemented Interfaces:
    java.io.Serializable, org.jaxen.Navigator
    public class DomTripNavigator
extends org.jaxen.DefaultNavigator
    Jaxen Navigator implementation for the DomTrip XML object model.

    This navigator enables full XPath 1.0 evaluation against DomTrip's lossless XML tree. It maps DomTrip's node types (Element, Text, Comment, ProcessingInstruction, Document) to Jaxen's expected navigation model.

    Since DomTrip's Attribute class does not extend Node and does not store a parent reference, this navigator uses AttributeNode wrappers on the attribute axis. Similarly, NamespaceNode wrappers represent namespace declarations on the namespace axis.

    Usage:

    
 Navigator nav = DomTripNavigator.getInstance();
 DomTripXPath xpath = new DomTripXPath("//dependency[@scope='test']");
 List results = xpath.selectNodes(root);
    Since:
    1.3.0
