All SAX parsers must implement this basic interface: it allows applications to register handlers for different types of events and to initiate a parse from a URI, or a character stream. All SAX parsers must also implement a zero-argument constructor (though other constructors are also allowed). SAX parsers are reusable but not re-entrant: the application may reuse a parser object (possibly with a different input source) once the first parse has completed successfully, but it may not invoke the parse() methods recursively within a parse.

Member Function Documentation virtual void Parser::parse (  const char *const    systemId )  [pure virtual]   Parse an XML document from a system identifier (URI). This method is a shortcut for the common case of reading a document from a system identifier. It is the exact equivalent of the following: parse(new URLInputSource(systemId)); If the system identifier is a URL, it must be fully resolved by the application before it is passed to the parser. Parameters: systemId  The system identifier (URI). Exceptions: SAXException  Any SAX exception, possibly wrapping another exception. XMLException  An exception from the parser or client handler code. See also: parse(InputSource) Implemented in SAXParser. virtual void Parser::parse (  const XMLCh *const    systemId )  [pure virtual]   Parse an XML document from a system identifier (URI). This method is a shortcut for the common case of reading a document from a system identifier. It is the exact equivalent of the following: parse(new URLInputSource(systemId)); If the system identifier is a URL, it must be fully resolved by the application before it is passed to the parser. Parameters: systemId  The system identifier (URI). Exceptions: SAXException  Any SAX exception, possibly wrapping another exception. XMLException  An exception from the parser or client handler code. See also: parse(InputSource) Implemented in SAXParser. virtual void Parser::parse (  const InputSource &    source )  [pure virtual]   Parse an XML document. The application can use this method to instruct the SAX parser to begin parsing an XML document from any valid input source (a character stream, a byte stream, or a URI). Applications may not invoke this method while a parse is in progress (they should create a new Parser instead for each additional XML document). Once a parse is complete, an application may reuse the same Parser object, possibly with a different input source. Parameters: source  The input source for the top-level of the XML document. Exceptions: SAXException  Any SAX exception, possibly wrapping another exception. XMLException  An exception from the parser or client handler code. See also: InputSource::InputSource , setEntityResolver , setDTDHandler , setDocumentHandler , setErrorHandler Implemented in SAXParser. virtual void Parser::setDocumentHandler (  DocumentHandler *const    handler )  [pure virtual]   Allow an application to register a document event handler. If the application does not register a document handler, all document events reported by the SAX parser will be silently ignored (this is the default behaviour implemented by HandlerBase). Applications may register a new or different handler in the middle of a parse, and the SAX parser must begin using the new handler immediately. Parameters: handler  The document handler. See also: DocumentHandler::DocumentHandler , HandlerBase::HandlerBase Implemented in SAXParser. virtual void Parser::setDTDHandler (  DTDHandler *const    handler )  [pure virtual]   Allow an application to register a DTD event handler. If the application does not register a DTD handler, all DTD events reported by the SAX parser will be silently ignored (this is the default behaviour implemented by HandlerBase). Applications may register a new or different handler in the middle of a parse, and the SAX parser must begin using the new handler immediately. Parameters: handler  The DTD handler. See also: DTDHandler::DTDHandler , HandlerBase::HandlerBase Implemented in SAXParser. virtual void Parser::setEntityResolver (  EntityResolver *const    resolver )  [pure virtual]   Allow an application to register a custom entity resolver. If the application does not register an entity resolver, the SAX parser will resolve system identifiers and open connections to entities itself (this is the default behaviour implemented in HandlerBase). Applications may register a new or different entity resolver in the middle of a parse, and the SAX parser must begin using the new resolver immediately. Parameters: resolver  The object for resolving entities. See also: EntityResolver::EntityResolver , HandlerBase::HandlerBase Implemented in SAXParser. virtual void Parser::setErrorHandler (  ErrorHandler *const    handler )  [pure virtual]   Allow an application to register an error event handler. If the application does not register an error event handler, all error events reported by the SAX parser will be silently ignored, except for fatalError, which will throw a SAXException (this is the default behaviour implemented by HandlerBase). Applications may register a new or different handler in the middle of a parse, and the SAX parser must begin using the new handler immediately. Parameters: handler  The error handler. See also: ErrorHandler::ErrorHandler , SAXException::SAXException , HandlerBase::HandlerBase Implemented in SAXParser.
