## Interface XMLEntityResolver

-     public interface XMLEntityResolver

  This interface is used to resolve external parsed entities. The application can register an object that implements this interface with the parser configuration in order to intercept entities and resolve them explicitly. If the registered entity resolver cannot resolve the entity, it should return `null` so that the parser will try to resolve the entity using a default mechanism.
