getDTDGrammar

public DTDGrammar getDTDGrammar()

getDTDGrammar

Returns:

the grammar created by this parser

startEntity

public void startEntity(java.lang.String name,
                        java.lang.String publicId,
                        java.lang.String systemId,
                        java.lang.String encoding)
                 throws 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:

XNIException - Thrown by handler to signal an error.

textDecl

public void textDecl(java.lang.String version,
                     java.lang.String encoding)
              throws 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:

XNIException - Thrown by handler to signal an error.

startDTD

public void startDTD(XMLLocator locator,
                     Augmentations augmentations)
              throws XNIException

The start of the DTD.

Specified by:

startDTD in interface XMLDTDHandler

Parameters:

locator - The document locator, or null if the document location cannot be reported during the parsing of the document DTD. However, it is strongly recommended that a locator be supplied that can at least report the base system identifier of the DTD.

augmentations - Additional information that may include infoset augmentations.

Throws:

XNIException - Thrown by handler to signal an error.

comment

public void comment(XMLString text,
                    Augmentations augmentations)
             throws XNIException

A comment.

Specified by:

comment in interface XMLDTDHandler

Parameters:

text - The text in the comment.

augmentations - Additional information that may include infoset augmentations.

Throws:

XNIException - Thrown by application to signal an error.

processingInstruction

public void processingInstruction(java.lang.String target,
                                  XMLString data,
                                  Augmentations augmentations)
                           throws 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.

Specified by:

processingInstruction in interface XMLDTDHandler

Parameters:

target - The target.

data - The data or null if none specified.

augmentations - Additional information that may include infoset augmentations.

Throws:

XNIException - Thrown by handler to signal an error.
