pure virtual

This method returns the state of the parser's exit-on-First-Fatal-Error flag.

Or you can query the feature "http://apache.org/xml/features/continue-after-fatal-error" which indicates the opposite state.

Returns
  true, if the parser is currently configured to exit on the first fatal error, false otherwise.

pure virtual

Query the current state of any feature in a SAX2 XMLReader.

Parameters

  name | The unique identifier (URI) of the feature being set.

Returns
  The current state of the feature.

Exceptions

## getProperty()

virtual void* SAX2XMLReader::getProperty | ( | const XMLCh *const | name | ) | const

pure virtual

Query the current value of a property in a SAX2 XMLReader.

The parser owns the returned pointer. The memory allocated for the returned pointer will be destroyed when the parser is deleted.

To ensure accessibility of the returned information after the parser is deleted, callers need to copy and store the returned information somewhere else; otherwise you may get unexpected result. Since the returned pointer is a generic void pointer, see the SAX2 Programming Guide to learn exactly what type of property value each property returns for replication.

Parameters

  name | The unique identifier (URI) of the property being set.

Returns
  The current value of the property. The pointer spans the same life-time as the parser. A null pointer is returned if nothing was specified externally.

See also
  setValidationConstraintFatal
  getFeature

## getValidator()

virtual XMLValidator* SAX2XMLReader::getValidator | ( |  | ) | const

pure virtual

## parse() [1/3]

virtual void SAX2XMLReader::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(const InputSource&)

## parse() [2/3]

virtual void SAX2XMLReader::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.

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

## parseFirst() [1/3]

virtual bool SAX2XMLReader::parseFirst | ( | const char *const | systemId,
|  | XMLPScanToken & | toFill
| ) |  |

pure virtual

Begin a progressive parse operation.

This method is used to start a progressive parse on a XML file. To continue parsing, subsequent calls must be to the parseNext method.

It scans through the prolog and returns a token to be used on subsequent scanNext() calls. If the return value is true, then the token is legal and ready for further use. If it returns false, then the scan of the prolog failed and the token is not going to work on subsequent scanNext() calls.

Parameters

  systemId | A pointer to a regular native string representing the path to the XML file to be parsed.
  toFill | A token maintaing state information to maintain internal consistency between invocation of 'parseNext' calls.

Returns
  'true', if successful in parsing the prolog. It indicates the user can go ahead with parsing the rest of the file. It returns 'false' to indicate that the parser could not parse the prolog.

## parseFirst() [2/3]

virtual bool SAX2XMLReader::parseFirst | ( | const InputSource & | source,
|  | XMLPScanToken & | toFill
| ) |  |

pure virtual

Begin a progressive parse operation.

This method is used to start a progressive parse on a XML file. To continue parsing, subsequent calls must be to the parseNext method.

It scans through the prolog and returns a token to be used on subsequent scanNext() calls. If the return value is true, then the token is legal and ready for further use. If it returns false, then the scan of the prolog failed and the token is not going to work on subsequent scanNext() calls.

Parameters

  source | A const reference to the InputSource object which points to the XML file to be parsed.
  toFill | A token maintaing state information to maintain internal consistency between invocation of 'parseNext' calls.

Returns
  'true', if successful in parsing the prolog. It indicates the user can go ahead with parsing the rest of the file. It returns 'false' to indicate that the parser could not parse the prolog.

## parseFirst() [3/3]

virtual bool SAX2XMLReader::parseFirst | ( | const XMLCh *const | systemId,
|  | XMLPScanToken & | toFill
| ) |  |

pure virtual

Begin a progressive parse operation.

This method is used to start a progressive parse on a XML file. To continue parsing, subsequent calls must be to the parseNext method.

It scans through the prolog and returns a token to be used on subsequent scanNext() calls. If the return value is true, then the token is legal and ready for further use. If it returns false, then the scan of the prolog failed and the token is not going to work on subsequent scanNext() calls.

Parameters

  systemId | A pointer to a Unicode string representing the path to the XML file to be parsed.
  toFill | A token maintaing state information to maintain internal consistency between invocation of 'parseNext' calls.

Returns
  'true', if successful in parsing the prolog. It indicates the user can go ahead with parsing the rest of the file. It returns 'false' to indicate that the parser could parse the prolog (which means the token will not be valid.)

See also
  parseNext
  #parseFirst(char*,...)
  #parseFirst(InputSource&,...)

## parseNext()

virtual bool SAX2XMLReader::parseNext | ( | XMLPScanToken & | token | ) |

pure virtual

Continue a progressive parse operation.

This method is used to continue with progressive parsing of XML files started by a call to 'parseFirst' method.

It parses the XML file and stops as soon as it comes across a XML token (as defined in the XML specification). Relevant callback handlers are invoked as required by the SAX specification.

Parameters

  token | A token maintaing state information to maintain internal consistency between invocation of 'parseNext' calls.

Returns
  'true', if successful in parsing the next XML token. It indicates the user can go ahead with parsing the rest of the file. It returns 'false' to indicate that the parser could not find next token as per the XML specification production rule.

  #parseFirst(XMLCh*,...)
  #parseFirst(char*,...)
  #parseFirst(InputSource&,...)

## parseReset()

virtual void SAX2XMLReader::parseReset | ( | XMLPScanToken & | token | ) |

pure virtual

Reset the parser after a progressive parse.

If a progressive parse loop exits before the end of the document is reached, the parser has no way of knowing this. So it will leave open any files or sockets or memory buffers that were in use at the time that the parse loop exited.

The next parse operation will cause these open files and such to be closed, but the next parse operation might occur at some unknown future point. To avoid this problem, you should reset the parser if you exit the loop early.

If you exited because of an error, then this cleanup will be done for you. Its only when you exit the file prematurely of your own accord, because you've found what you wanted in the file most likely.

Parameters

  token | A token maintaing state information to maintain internal consistency between invocation of 'parseNext' calls.

## removeAdvDocHandler()

virtual bool SAX2XMLReader::removeAdvDocHandler | ( | XMLDocumentHandler *const | toRemove | ) |

## setContentHandler()

virtual void SAX2XMLReader::setContentHandler | ( | ContentHandler *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.

If the application does not register a declaration handler, all events reported by the SAX parser will be silently ignored. (this is the default behaviour implemented by DefaultHandler).

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 declaration handler.

See also
  DeclHandler::DeclHandler
  SAXException::SAXException

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 DefaultHandler).

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
  DefaultHandler::DefaultHandler

## setErrorHandler()

virtual void SAX2XMLReader::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

## setExitOnFirstFatalError()

virtual void SAX2XMLReader::setExitOnFirstFatalError | ( | const bool | newState | ) |

pure virtual

This method allows users to set the parser's behaviour when it encounters the first fatal error.

If set to true, the parser will exit at the first fatal error. If false, then it will report the error and continue processing.

The default value is 'true' and the parser exits on the first fatal error.

Or you can set the feature "http://apache.org/xml/features/continue-after-fatal-error" which has the opposite behaviour.

If both the feature above and this function are used, the latter takes effect.

Parameters

  newState | The value specifying whether the parser should continue or exit when it encounters the first fatal error.

It takes a void pointer as the property value. Application is required to initialize this void pointer to a correct type. See the SAX2 Programming Guide to learn exactly what type of property value each property expects for processing. Passing a void pointer that was initialized with a wrong type will lead to unexpected result. If the same property is set more than once, the last one takes effect.

Parameters

  name | The unique identifier (URI) of the property being set.
  value | The requested value for the property. See the SAX2 Programming Guide to learn exactly what type of property value each property expects for processing. Passing a void pointer that was initialized with a wrong type will lead to unexpected result.

Exceptions

  SAXNotRecognizedException | If the requested property is not known.
  SAXNotSupportedException | Property modification is not supported during parse

## setValidationConstraintFatal()

virtual void SAX2XMLReader::setValidationConstraintFatal | ( | const bool | newState | ) |

pure virtual

This method allows users to set the parser's behaviour when it encounters a validation constraint error.

If set to true, and the the parser will treat validation error as fatal and will exit depends on the state of "getExitOnFirstFatalError". If false, then it will report the error and continue processing.

Note: setting this true does not mean the validation error will be printed with the word "Fatal Error". It is still printed as "Error", but the parser will exit if "setExitOnFirstFatalError" is set to true.

The default value is 'false'.

Or you can set the feature "http://apache.org/xml/features/validation-error-as-fatal" which means the same thing.

If both the feature above and this function are used, the latter takes effect.

Parameters

  newState | If true, the parser will exit if "setExitOnFirstFatalError" is set to true.

## setValidator()

virtual void SAX2XMLReader::setValidator | ( | XMLValidator * | valueToAdopt | ) |

pure virtual

This method is used to set a validator.

SAX2XMLReader assumes responsibility for the validator. It will be deleted when the XMLReader is destroyed.

Parameters

  valueToAdopt | A pointer to the validator that the reader should use.
