## Detailed Description

This class implements the Document Object Model (DOM) interface.

It should be used by applications which choose to parse and process the XML document using the DOM api's. This implementation also allows the applications to install an error and an entity handler (useful extensions to the DOM specification).

It can be used to instantiate a validating or non-validating parser, by setting a member flag.

## Constructor & Destructor Documentation

## ◆ XercesDOMParser()

XercesDOMParser::XercesDOMParser | ( | XMLValidator *const | valToAdopt = `0`,
|  | MemoryManager *const | manager = `XMLPlatformUtils::fgMemoryManager`,
|  | XMLGrammarPool *const | gramPool = `0`
| ) |  |

Construct a XercesDOMParser, with an optional validator.

Constructor with an instance of validator class to use for validation. If you don't provide a validator, a default one will be created for you in the scanner.

Parameters

  gramPool | Pointer to the grammar pool instance from external application. The parser does NOT own it.
  valToAdopt | Pointer to the validator instance to use. The parser is responsible for freeing the memory.
  manager | Pointer to the memory manager to be used to allocate objects.

## ◆ ~XercesDOMParser()

virtual XercesDOMParser::~XercesDOMParser | ( |  | ) |
| virtual

Destructor.

## Member Function Documentation

## ◆ cacheGrammarFromParse()

void XercesDOMParser::cacheGrammarFromParse | ( | const bool | newState | ) |

Set the 'Grammar caching' flag.

This method allows users to enable or disable caching of grammar when parsing XML documents. When set to true, the parser will cache the resulting grammar for use in subsequent parses.

If the flag is set to true, the 'Use cached grammar' flag will also be set to true.

The parser's default state is: false.

Parameters

  newState | The value specifying whether we should cache grammars or not.

  isCachingGrammarFromParse
  useCachedGrammarInParse

## ◆ endInputSource()

void XercesDOMParser::endInputSource | ( | const InputSource & | inputSource | ) |
| virtual

Handle an end of input source event.

This method is used to indicate the end of parsing of an external entity file.

This method is a no-op for this DOM implementation.

Parameters

  inputSource | A const reference to the InputSource object which points to the XML file being parsed.

| ) |  |
| virtual

Handle errors reported from the parser.

This method is used to report back errors found while parsing the XML file. This method is also borrowed from the SAX specification. It calls the corresponding user installed Error Handler method: 'fatal', 'error', 'warning' depending on the severity of the error. This classification is defined by the XML specification.

Parameters

  errCode | An integer code for the error.
  msgDomain | A const pointer to an Unicode string representing the message domain to use.
  errType | An enumeration classifying the severity of the error.
  errorText | A const pointer to an Unicode string representing the text of the error message.
  systemId | A const pointer to an Unicode string representing the system id of the XML file where this error was discovered.
  publicId | A const pointer to an Unicode string representing the public id of the XML file where this error was discovered.
  lineNum | The line number where the error occurred.
  colNum | The column number where the error occurred.

Preparse schema grammar (XML Schema, DTD, etc.) via a file path or URL.

This method invokes the preparsing process on a schema grammar XML file specified by the file path parameter. If the 'toCache' flag is enabled, the parser will cache the grammars for re-use. If a grammar key is found in the pool, no caching of any grammar will take place.

Parameters

  systemId | A const char pointer to a native string which contains the path to the XML grammar file to be preparsed.
  grammarType | The grammar type (Schema or DTD).
  toCache | If `true`, we cache the preparsed grammar, otherwise, no caching. Default is `false`.

Returns
  The preparsed schema grammar object (SchemaGrammar or DTDGrammar). That grammar object is owned by the parser.

Exceptions

  SAXException | Any SAX exception, possibly wrapping another exception.
  XMLException | An exception from the parser or client handler code.
  DOMException | A DOM exception as per DOM spec.

## ◆ resetCachedGrammarPool()

void XercesDOMParser::resetCachedGrammarPool | ( |  | ) |

This method allows the user to reset the pool of cached grammars.

## ◆ resetDocumentPool()

void XercesDOMParser::resetDocumentPool | ( |  | ) |

Reset the documents vector pool and release all the associated memory back to the system.

When parsing a document using a DOM parser, all memory allocated for a DOM tree is associated to the DOM document.

If you do multiple parse using the same DOM parser instance, then multiple DOM documents will be generated and saved in a vector pool. All these documents (and thus all the allocated memory) won't be deleted until the parser instance is destroyed.

If you don't need these DOM documents anymore and don't want to destroy the DOM parser instance at this moment, then you can call this method to reset the document vector pool and release all the allocated memory back to the system.

It is an error to call this method if you are in the middle of a parse (e.g. in the mid of a progressive parse).

Exceptions

  IOException | An exception from the parser if this function is called when a parse is in progress.

## ◆ resetEntities()

void XercesDOMParser::resetEntities | ( |  | ) |
| virtual

Reset any entity handler information.

This method allows the installed XMLEntityHandler to reset itself.

This method is a no-op for this DOM implementation.

Implements XMLEntityHandler.

## ◆ resetErrors()

virtual void XercesDOMParser::resetErrors | ( |  | ) |
| virtual

Reset any error data before a new parse.

This method allows the user installed Error Handler callback to 'reset' itself.

This method is a no-op for this DOM implementation.

Implements XMLErrorReporter.

## ◆ resolveEntity()

virtual InputSource* XercesDOMParser::resolveEntity | ( | XMLResourceIdentifier * | resourceIdentifier | ) |
| virtual

Resolve a public/system id.

This method allows a user installed entity handler to further process any pointers to external entities. The applications can implement 'redirection' via this callback.

Parameters

  resourceIdentifier | An object containing the type of resource to be resolved and the associated data members corresponding to this type.

Returns
  The value returned by the user installed resolveEntity method or NULL otherwise to indicate no processing was done. The returned InputSource is owned by the parser which is responsible to clean up the memory.

Implements XMLEntityHandler.

## ◆ setEntityResolver()

void XercesDOMParser::setEntityResolver | ( | EntityResolver *const | handler | ) |

Set the entity resolver.

This method allows applications to install their own entity resolver. By installing an entity resolver, the applications can trap and potentially redirect references to external entities.

Any previously set entity resolver is merely dropped, since the parser does not own them. If both setEntityResolver and setXMLEntityResolver are called, then the last one is used.

Parameters

  handler | A const pointer to the user supplied entity resolver.

  getEntityResolver

## ◆ setErrorHandler()

void XercesDOMParser::setErrorHandler | ( | ErrorHandler *const | handler | ) |

Set the error handler.

This method allows applications to install their own error handler to trap error and warning messages.

Any previously set handler is merely dropped, since the parser does not own them.

Parameters

  handler | A const pointer to the user supplied error handler.

See also
  getErrorHandler

## ◆ setIgnoreCachedDTD()

void XercesDOMParser::setIgnoreCachedDTD | ( | const bool | newValue | ) |

Set the 'ignore cached DTD grammar' flag.

This method gives users the option to ignore a cached DTD grammar, when an XML document contains both an internal and external DTD, and the use cached grammar from parse option is enabled. Currently, we do not allow using cached DTD grammar when an internal subset is present in the document. This option will only affect the behavior of the parser when an internal and external DTD both exist in a document (i.e. no effect if document has no internal subset).

The parser's default state is false

Parameters

  newValue | The state to set

## ◆ setXMLEntityResolver()

void XercesDOMParser::setXMLEntityResolver | ( | XMLEntityResolver *const | handler | ) |

Set the entity resolver.

This method allows applications to install their own entity resolver. By installing an entity resolver, the applications can trap and potentially redirect references to external entities.

Any previously set entity resolver is merely dropped, since the parser does not own them. If both setEntityResolver and setXMLEntityResolver are called, then the last one set is used.

Parameters

  handler | A const pointer to the user supplied entity resolver.

See also
  getXMLEntityResolver

## ◆ startInputSource()

void XercesDOMParser::startInputSource | ( | const InputSource & | inputSource | ) |
| virtual

Handle a 'start input source' event.

This method is used to indicate the start of parsing an external entity file.

This method is a no-op for this DOM parse implementation.

Parameters

  inputSource | A const reference to the InputSource object which points to the external entity being parsed.

Implements XMLEntityHandler.

## ◆ useCachedGrammarInParse()

void XercesDOMParser::useCachedGrammarInParse | ( | const bool | newState | ) |

Set the 'Use cached grammar' flag.

This method allows users to enable or disable the use of cached grammars. When set to true, the parser will use the cached grammar, instead of building the grammar from scratch, to validate XML documents.

If the 'Grammar caching' flag is set to true, this method ignore the value passed in.

The parser's default state is: false.

Parameters

  newState | The value specifying whether we should use the cached grammar or not.
