Handling DTDs

• The DTDHandler interface covers those aspects of DTDs a non-validating parser may care about and are not handled by other interfaces:

  • Notation Declarations

  • Unparsed Entity Declarations

• Attribute Defaults are handled transparently by startElement() and the Attributes interface

• Parsed entities are handled transparently by ContentHandler unless you install an EntityResolver

• The DTDHandler interface:

  package org.xml.sax;
  
  public interface DTDHandler {
         
    public void notationDecl(String name, String publicId, String systemId)
     throws SAXException;
   
    public void unparsedEntityDecl(String name, String publicId, 
     String systemId, String notationName) throws SAXException;
      
  }
