Method Detail

### getDTDGrammar

    public DTDGrammar getDTDGrammar()

                     throws org.apache.xerces.xni.XNIException

  This method notifies of the start of an entity. The DTD has the pseudo-name of "[dtd]" and parameter entity names start with '%'.

  Note: Since the DTD is an entity, the handler will be notified of the start of the DTD entity by calling the startEntity method with the entity name "[dtd]" before calling the startDTD method.

  Parameters:
    `name` - The name of the entity.
    `publicId` - The public identifier of the entity if the entity is external, null otherwise.
    `systemId` - The system identifier of the entity if the entity is external, null otherwise.
    `encoding` - The auto-detected IANA encoding name of the entity stream. This value will be null in those situations where the entity encoding is not auto-detected (e.g. internal parameter entities).
  Throws:
    `org.apache.xerces.xni.XNIException` - Thrown by handler to signal an error.

                  throws org.apache.xerces.xni.XNIException

  Notifies of the presence of a TextDecl line in an entity. If present, this method will be called immediately following the startEntity call.

  Note: This method is only called for external parameter entities referenced in the DTD.

  Parameters:
    `version` - The XML version, or null if not specified.
    `encoding` - The IANA encoding name of the entity.
  Throws:
    `org.apache.xerces.xni.XNIException` - Thrown by handler to signal an error.

                               throws org.apache.xerces.xni.XNIException

  A processing instruction. Processing instructions consist of a target name and, optionally, text data. The data is only meaningful to the application.

  Typically, a processing instruction's data will contain a series of pseudo-attributes. These pseudo-attributes follow the form of element attributes but are not parsed or presented to the application as anything other than text. The application is responsible for parsing the data.
