Interface DeclHandler
- DefaultHandler2
SAX2 extension handler for DTD declaration events.
This module, both source code and documentation, is in the
Public Domain, and comes with NO WARRANTY.
See http://www.saxproject.org
for further information.
This is an optional extension handler for SAX2 to provide more
complete information about DTD declarations in an XML document.
XML readers are not required to recognize this handler, and it
is not part of core-only SAX2 distributions.
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 property name
http://xml.org/sax/properties/declaration-handler
and an object implementing this interface (or null) as the value.
If the reader does not report declaration events, it will throw a
SAXNotRecognizedException
when you attempt to register the handler.
attributeDecl
public abstract void attributeDecl(String eName,
String aName,
String type,
String mode,
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", 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.
The value will be the value as reported to applications,
appropriately normalized and with entity and character
references expanded.
eName - The name of the associated element.aName - The name of the attribute.type - A string representing the attribute type.mode - A string representing the attribute defaulting mode
("#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.
elementDecl
public abstract 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.
name - The element type name.model - The content model as a normalized string.
externalEntityDecl
public abstract void externalEntityDecl(String name,
String publicId,
String systemId)
throws SAXException Report a parsed external entity declaration.
Only the effective (first) declaration for each entity
will be reported.
If the system identifier is a URL, the parser must resolve it
fully before passing it to the application.
name - The name of the entity. If it is a parameter
entity, the name will begin with '%'.publicId - The entity's public identifier, or null if none
was given.systemId - The entity's system identifier.
internalEntityDecl
public abstract 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.
name - The name of the entity. If it is a parameter
entity, the name will begin with '%'.value - The replacement text of the entity.
