All Known Implementing Classes:

public interface DeclHandler

SAX2 extension handler for DTD declaration events.

This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY.

This is an optional extension handler for SAX2 to provide information about DTD declarations in an XML document. XML readers are not required to support this handler.

Note that data-related DTD declarations (unparsed entities and notations) are already reported through the DTDHandler interface.

If you are using the declaration handler together with a lexical handler, all of the events will occur between the startDTD and the endDTD events.

To set the DeclHandler for an XML reader, use the setProperty method with the propertyId "http://xml.org/sax/handlers/DeclHandler". If the reader does not support declaration events, it will throw a SAXNotRecognizedException or a SAXNotSupportedException when you attempt to register the handler.

SAX 2.0

2.0beta

Method Detail

elementDecl

public void elementDecl(java.lang.String name,
                        java.lang.String model)
                 throws SAXException
Report an element type declaration.

The content model will consist of the string "EMPTY", the string "ANY", or a parenthesised group, optionally followed by an occurrence indicator. The model will be normalized so that all whitespace is removed,and will include the enclosing parentheses.

Parameters:
name - The element type name.
model - The content model as a normalized string.
Throws:
SAXException - The application may raise an exception.

attributeDecl

public void attributeDecl(java.lang.String eName,
                          java.lang.String aName,
                          java.lang.String type,
                          java.lang.String valueDefault,
                          java.lang.String value)
                   throws SAXException
Report an attribute type declaration.

Only the effective (first) declaration for an attribute will be reported. The type will be one of the strings "CDATA", "ID", "IDREF", "IDREFS", "NMTOKEN", "NMTOKENS", "ENTITY", "ENTITIES", or "NOTATION", or a parenthesized token group with the separator "|" and all whitespace removed.

Parameters:
eName - The name of the associated element.
aName - The name of the attribute.
type - A string representing the attribute type.
valueDefault - A string representing the attribute default ("#IMPLIED", "#REQUIRED", or "#FIXED") or null if none of these applies.
value - A string representing the attribute's default value, or null if there is none.
Throws:
SAXException - The application may raise an exception.

internalEntityDecl

public void internalEntityDecl(java.lang.String name,
                               java.lang.String value)
                        throws SAXException
Report an internal entity declaration.

Only the effective (first) declaration for each entity will be reported.

Parameters:
name - The name of the entity. If it is a parameter entity, the name will begin with '%'.
value - The replacement text of the entity.
Throws:
SAXException - The application may raise an exception.

externalEntityDecl

public void externalEntityDecl(java.lang.String name,
                               java.lang.String publicId,
                               java.lang.String systemId)
                        throws SAXException
Report a parsed external entity declaration.

Only the effective (first) declaration for each entity will be reported.

Parameters:
name - The name of the entity. If it is a parameter entity, the name will begin with '%'.
publicId - The declared public identifier of the entity, or null if none was declared.
systemId - The declared system identifier of the entity.
Throws:
SAXException - The application may raise an exception.
