Constructor & Destructor Documentation

virtual AbstractDOMParser::~AbstractDOMParser ( ) [virtual]

Destructor.

AbstractDOMParser::AbstractDOMParser ( XMLValidator *const valToAdopt = 0,

MemoryManager *const manager = XMLPlatformUtils::fgMemoryManager,

XMLGrammarPool *const gramPool = 0

) [protected]

Construct a AbstractDOMParser, 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:

valToAdopt Pointer to the validator instance to use. The parser is responsible for freeing the memory.

gramPool Pointer to the grammar pool instance from external application (through derivatives). The parser does NOT own it.

manager Pointer to the memory manager to be used to allocate objects.

Member Function Documentation

DOMDocument* AbstractDOMParser::adoptDocument ( )

Adopt the DOM document.
This method returns the DOMDocument object representing the root of the document tree.
The caller will adopt the DOMDocument and thus is responsible to call DOMDocument::release() to release the associated memory. The parser will not delete it. The ownership is transferred from the parser to the caller.

Returns:
The adopted DOMDocument object which represents the entire XML document.

virtual void AbstractDOMParser::attDef ( const DTDElementDecl & elemDecl,

const DTDAttDef & attDef,

const bool ignoring

) [virtual]

const XMLCh * qualifiedName

) [protected, virtual]

virtual void AbstractDOMParser::docCharacters ( const XMLCh *const chars,

const unsigned int length,

const bool cdataSection

) [virtual]

Handle document character events.
This method is used to report all the characters scanned by the parser. This DOM implementation stores this data in the appropriate DOM node, creating one if necessary.
Parameters:

chars A const pointer to a Unicode string representing the character data.

length The length of the Unicode string returned in 'chars'.

cdataSection A flag indicating if the characters represent content from the CDATA section.

Implements XMLDocumentHandler.

virtual void AbstractDOMParser::docComment ( const XMLCh *const comment ) [virtual]

Handle a document comment event.
This method is used to report any comments scanned by the parser. A new comment node is created which stores this data.
Parameters:

comment A const pointer to a null terminated Unicode string representing the comment text.

Implements XMLDocumentHandler.

virtual void AbstractDOMParser::docPI ( const XMLCh *const target,

const XMLCh *const data

) [virtual]

Handle a document PI event.
This method is used to report any PI scanned by the parser. A new PI node is created and appended as a child of the current node in the tree.
Parameters:

target A const pointer to a Unicode string representing the target of the PI declaration.

data A const pointer to a Unicode string representing the data of the PI declaration. See the PI production rule in the XML specification for details.

Implements XMLDocumentHandler.

virtual void AbstractDOMParser::elementTypeInfo ( const XMLCh *const typeName,

const XMLCh *const typeURI

) [virtual]

Receive notification of the name and namespace of the type that validated the element corresponding to the most recent endElement event.
This event will be fired immediately after the endElement() event that signifies the end of the element to which it applies; no other events will intervene. This method is <emEXPERIMENTAL and may change, disappear or become pure virtual at any time.
This corresponds to a part of the information required by DOM Core level 3's TypeInfo interface.
Parameters:

typeName local name of the type that actually validated the content of the element corresponding to the most recent endElement() callback

typeURI namespace of the type that actually validated the content of the element corresponding to the most recent endElement() callback @experimental

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.

systemId A pointer to a Unicode string represting 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.

bool AbstractDOMParser::parseNext ( XMLPScanToken & token )

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).
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.
See also:
parseFirst(XMLCh*,...) , parseFirst(char*,...) , parseFirst(InputSource&,...)

void AbstractDOMParser::parseReset ( XMLPScanToken & token )

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.

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

If this method is called more than once, only the last one takes effect.
The syntax is the same as for the noNamespaceSchemaLocation attribute that may occur in an instance document: e.g."file_name.xsd".
Parameters:

noNamespaceSchemaLocation the XML Schema Location with no target namespace

See also:
getExternalNoNamespaceSchemaLocation

void AbstractDOMParser::setExternalSchemaLocation ( const char *const schemaLocation )

This method is same as setExternalSchemaLocation(const XMLCh* const).

schemaLocation the list of schemas to use

See also:
setExternalSchemaLocation(const XMLCh* const)

void AbstractDOMParser::setExternalSchemaLocation ( const XMLCh *const schemaLocation )

This method allows the user to specify a list of schemas to use.
If the targetNamespace of a schema specified using this method matches the targetNamespace of a schema occuring in the instance document in the schemaLocation attribute, or if the targetNamespace matches the namespace attribute of the "import" element, the schema specified by the user using this method will be used (i.e., the schemaLocation attribute in the instance document or on the "import" element will be effectively ignored).
If this method is called more than once, only the last one takes effect.
The syntax is the same as for schemaLocation attributes in instance documents: e.g, "http://www.example.com file_name.xsd". The user can specify more than one XML Schema in the list.
Parameters:

schemaLocation the list of schemas to use

See also:
getExternalSchemaLocation

void AbstractDOMParser::setIncludeIgnorableWhitespace ( const bool include )

Set the 'include ignorable whitespace' flag.
This method allows the user to specify whether a validating parser should include ignorable whitespaces as text nodes. It has no effect on non-validating parsers which always include non-markup text.
When set to true (also the default), ignorable whitespaces will be added to the DOM tree as text nodes. The method DOMText::isIgnorableWhitespace() will return true for those text nodes only.
When set to false, all ignorable whitespace will be discarded and no text node is added to the DOM tree. Note: applications intended to process the "xml:space" attribute should not set this flag to false. And this flag also overrides any schema datateye whitespace facets, that is, all ignorable whitespace will be discarded even though 'preserve' is set in schema datatype whitespace facets.
Parameters:

include The new state of the include ignorable whitespace flag.

See also:
getIncludeIgnorableWhitespace

void AbstractDOMParser::setLoadExternalDTD ( const bool newState )
