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 entitty handler (useful extensions to the DOM specification).
It can be used to instantiate a validating or non-validating parser, by setting a member flag.

|
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. |
reuseGrammar
|
The flag indicating whether the existing Grammar should be reused or not for this parsing process. If true, there cannot be any internal subset.
|
-
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.

void DOMParser::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.
|

void DOMParser::setCreateEntityReferenceNodes (
|
const bool create )
|
|
|
Set the 'include entity references' flag.
This method allows the user to specify whether the parser should create entity reference nodes in the DOM tree being produced. When the 'create' flag is true, the DOM tree constains entity reference nodes. When the 'create' flag is false, no entity reference nodes are included in the DOM tree.
The replacement text of the entity is included in either case, either as a child of the Entity Reference node or in place at the location of the reference. -
Parameters:

This method allows users to enable or disable the parser's namespace processing. When set to true, parser starts enforcing all the constraints and rules specified by the NameSpace specification.
The parser's default state is: false.
This flag is ignored by the underlying scanner if the installed validator indicates that namespace constraints should be enforced. -
Parameters:
-
newState
|
The value specifying whether NameSpace rules should be enforced or not.

|
-
See also:
-
getDoSchema
|
void DOMParser::setDoValidation (

-
getErrorHandler
|
void DOMParser::setExitOnFirstFatalError (
|
const bool newState )
|
|
|
Set the 'exit on first error' flag.
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. -
Parameters:
-
newState
|
The value specifying whether the parser should continue or exit when it encounters the first fatal error.

|
void DOMParser::setExpandEntityReferences (
|
const bool expand )
|
|
|
Set the 'expand entity references' flag.
DEPRECATED. USE setCreateEntityReferenceNodes instead. This method allows the user to specify whether the parser should expand all entity reference nodes. When the 'do expansion' flag is true, the DOM tree does not have any entity reference nodes. It is replaced by the sub-tree representing the replacement text of the entity. When the 'do expansion' flag is false, the DOM tree contains an extra entity reference node, whose children is the sub tree of the replacement text. -
Parameters:
-
expand
|
The new state of the expand entity reference flag. |
|
void DOMParser::setExternalNoNamespaceSchemaLocation (
|
const char *const noNamespaceSchemaLocation )
|
|
void DOMParser::setExternalNoNamespaceSchemaLocation (
|
const XMLCh * const )
|
|
|
This method allows the user to specify the no target namespace XML Schema Location externally.
If specified, the instance document's noNamespaceSchemaLocation attribute 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 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 DOMParser::setExternalSchemaLocation (
|
const char *const schemaLocation )
|
|
void DOMParser::setExternalSchemaLocation (
|
const XMLCh * const )
|
|
|
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
|
-

-
getExternalSchemaLocation
|
void DOMParser::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 DOM_Text::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 DOMParser::setToCreateXMLDeclTypeNode (
|
const bool create )
|
|
|

By setting it to 'true' user can have XMLDecl type nodes attached to the DOM tree.
The parser's default state is: false -
Parameters:
-
create
|
The new to create XMLDecl type node flag |
|
void DOMParser::setValidationConstraintFatal (
|
const bool newState )
|
|
|
This method allows users to set the parser's behaviour when it encounters a validtion constraint error.
If set to true, and the the parser is set to exit when it encounter the first fatal error, the parser will exit at the first encounter. If false, then it will report the error and continue processing.
The default value is 'false'. -
Parameters:
-
newState
|
The value specifying whether the parser should continue or exit when it encounters a validation constraint error.
|
-

getValidationConstraintFatal
|
void DOMParser::setValidationSchemaFullChecking (
|
const bool schemaFullChecking )
|
|
|
This method allows the user to turn full Schema constraint checking on/off.
Only takes effect if Schema validation is enabled. If turned off, partial constraint checking is done.
Full schema constraint checking includes those checking that may be time-consuming or memory intensive. Currently, particle unique attribution constraint checking and particle derivation resriction checking are controlled by this option.
The parser's default state is: false. -
Parameters:
-
schemaFullChecking
|
True to turn on full schema constraint checking.
|
-
