NamespaceContext

• Supply a NamespaceContext object to evaluate() that can resolve the prefixes:

  package javax.xml.namespace;
  
  public interface NamespaceContext {
  
   String   getNamespaceURI(String prefix);
   String   getPrefix(String namespaceURI);
   Iterator getPrefixes(String namespaceURI);
  
  }

• Java 7/JAXP 1.5 should add a standard implementation of this interface.
