XML in a Nutshell, 3rd Edition

Name

The EntityResolver Interface

Synopsis

By passing an instance of the EntityResolver interface to the setEntityResolver( ) method of XMLReader, you can intercept parser requests for external entities, such as the external DTD subset or external parameter entities, and redirect those requests in order to substitute different entities. For example, you could replace a reference to a remote copy of a standard DTD with a local one or find the sources for particular public IDs in a catalog.

package org.xml.sax;
     
public interface EntityResolver {
     
  public InputSource resolveEntity(String publicID, String systemID)
   throws SAXException, IOException;
     
}
