Detailed Description
The QXmlDeclHandler class provides an interface to report declaration
content of XML data.
You can set the declaration handler with
QXmlReader::setDeclHandler().
This interface is based on the SAX2 extension DeclHandler.
The interface provides attributeDecl(), internalEntityDecl() and
externalEntityDecl() functions.
See also the Introduction to SAX2.
See also QXmlDTDHandler, QXmlContentHandler, QXmlEntityResolver, QXmlErrorHandler, QXmlLexicalHandler, and XML.
Member Function Documentation
bool QXmlDeclHandler::attributeDecl ( const QString & eName, const QString & aName, const QString & type, const QString & valueDefault, const QString & value ) [pure virtual]
The reader calls this function to report an attribute type
declaration. Only the effective (first) declaration for an
attribute is reported.
The reader passes the name of the associated element in eName
and the name of the attribute in aName. It passes a string that
represents the attribute type in type and a string that
represents the attribute default in valueDefault. This string
is one of "#IMPLIED", "#REQUIRED", "#FIXED" or QString::null (if
none of the others applies). The reader passes the attribute's
default value in value. If no default value is specified in the
XML file, value is QString::null.
If this function returns FALSE the reader stops parsing and
reports an error. The reader uses the function errorString() to
get the error message.
QString QXmlDeclHandler::errorString () [pure virtual]
The reader calls this function to get an error string if any of
the handler functions returns FALSE.
bool QXmlDeclHandler::externalEntityDecl ( const QString & name, const QString & publicId, const QString & systemId ) [pure virtual]
The reader calls this function to report a parsed external entity
declaration. Only the effective (first) declaration for each
entity is reported.
The reader passes the name of the entity in name, the public
identifier in publicId and the system identifier in systemId. If there is no public identifier specified, it passes
QString::null in publicId.
If this function returns FALSE the reader stops parsing and
reports an error. The reader uses the function errorString() to
get the error message.
bool QXmlDeclHandler::internalEntityDecl ( const QString & name, const QString & value ) [pure virtual]
The reader calls this function to report an internal entity
declaration. Only the effective (first) declaration is reported.
The reader passes the name of the entity in name and the value
of the entity in value.
If this function returns FALSE the reader stops parsing and
reports an error. The reader uses the function errorString() to
get the error message.
