elementDecl
public void elementDecl(String name, 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 parameter entities are fully resolved and all whitespace is removed,and will include the enclosing parentheses. Other normalization (such as removing redundant parentheses or simplifying occurrence indicators) is at the discretion of the parser.
- Specified by:
elementDecl
in interfaceDeclHandler
- 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(String eName, String aName, String type, String valueDefault, String val) 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", a parenthesized token group with the separator "|" and all whitespace removed, or the word "NOTATION" followed by a space followed by a parenthesized token group with all whitespace removed.
Any parameter entities in the attribute value will be expanded, but general entities will not.
- Specified by:
attributeDecl
in interfaceDeclHandler
- 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.val
- 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(String name, String value) throws SAXException
Report an internal entity declaration.Only the effective (first) declaration for each entity will be reported. All parameter entities in the value will be expanded, but general entities will not.
- Specified by:
internalEntityDecl
in interfaceDeclHandler
- 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.- See Also:
externalEntityDecl(java.lang.String, java.lang.String, java.lang.String)

-
externalEntityDecl
public void externalEntityDecl(String name, String publicId, String sysId) throws SAXException
Report a parsed external entity declaration.Only the effective (first) declaration for each entity will be reported.
- Specified by:
externalEntityDecl
in interfaceDeclHandler
- 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.sysId

notationDecl
public void notationDecl(String name, String publicId, String systemId) throws SAXException
Receive notification of a notation declaration event.It is up to the application to record the notation for later reference, if necessary.
At least one of publicId and systemId must be non-null. If a system identifier is present, and it is a URL, the SAX parser must resolve it fully before passing it to the application through this event.
There is no guarantee that the notation declaration will be reported before any unparsed entities that use it.
- Specified by:
notationDecl
in interfaceDTDHandler
- Overrides:
notationDecl
in classDefaultHandler
- Parameters:
name
- The notation name.publicId
- The notation's public identifier, or null if none was given.systemId
- The notation's system identifier, or null if none was given.- Throws:
SAXException
- Any SAX exception, possibly wrapping another exception.- See Also:
unparsedEntityDecl(java.lang.String, java.lang.String, java.lang.String, java.lang.String)
,AttributeList
-
unparsedEntityDecl
public void unparsedEntityDecl(String name, String publicId, String systemId, String notationName) throws SAXException
Receive notification of an unparsed entity declaration event.Note that the notation name corresponds to a notation reported by the
notationDecl
event. It is up to the application to record the entity for later reference, if necessary.If the system identifier is a URL, the parser must resolve it fully before passing it to the application.
- Specified by:
unparsedEntityDecl
in interfaceDTDHandler
- Overrides:
unparsedEntityDecl
in classDefaultHandler
- Parameters:
name
- The unparsed entity's name.publicId
- The entity's public identifier, or null if none was given.systemId
- The entity's system identifier.notationName
- The name of the associated notation.- Throws:
SAXException
- Any SAX exception, possibly wrapping another exception.- See Also:
