org.apache.xml.security.utils.resolver.implementations.ResolverXPointer

public class ResolverXPointer
extends ResourceResolverSpi

Handles barename XPointer Reference URIs.

To retain comments while selecting an element by an identifier ID, use the following full XPointer: URI='#xpointer(id('ID'))'.

To retain comments while selecting the entire document, use the following full XPointer: URI='#xpointer(/)'. This XPointer contains a simple XPath expression that includes the root node, which the second to last step above replaces with all nodes of the parse tree (all descendants, plus all attributes, plus all namespaces nodes).
