DTDHandlerpublic interface DTDHandler Receive notification of basic DTD-related 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.
If a SAX application needs information about notations and
unparsed entities, then the application implements this
interface and registers an instance with the SAX parser using
the parser's setDTDHandler method. The parser uses the
instance to report notation and unparsed entity declarations to
the application.
Note that this interface includes only those DTD events that
the XML recommendation requires processors to report:
notation and unparsed entity declarations.
The SAX parser may report these events in any order, regardless
of the order in which the notations and unparsed entities were
declared; however, all DTD events must be reported after the
document handler's startDocument event, and before the first
startElement event.
(If the {@link org.xml.sax.ext.LexicalHandler LexicalHandler} is
used, these events must also be reported before the endDTD event.)
It is up to the application to store the information for
future use (perhaps in a hash table or object tree).
If the application encounters attributes of type "NOTATION",
"ENTITY", or "ENTITIES", it can use the information that it
obtained through this interface to find the entity and/or
notation corresponding with the attribute value. |
| Methods Summary |
|---|
| public abstract void | notationDecl(java.lang.String name, java.lang.String publicId, java.lang.String systemId)Receive notification of a notation declaration event.
It is up to the application to record the notation for later
reference, if necessary;
notations may appear as attribute values and in unparsed entity
declarations, and are sometime used with processing instruction
target names.
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.
| | public abstract void | unparsedEntityDecl(java.lang.String name, java.lang.String publicId, java.lang.String systemId, java.lang.String notationName)Receive notification of an unparsed entity declaration event.
Note that the notation name corresponds to a notation
reported by the {@link #notationDecl notationDecl} event.
It is up to the application to record the entity for later
reference, if necessary;
unparsed entities may appear as attribute values.
If the system identifier is a URL, the parser must resolve it
fully before passing it to the application.
