QXmlDeclHandler(3qt)QXmlDeclHandler(3qt)NAMEQXmlDeclHandler - Interface to report declaration content of XML data
SYNOPSIS
All the functions in this class are reentrant when Qt is built with
thread support.</p>
#include <qxml.h>
Inherited by QXmlDefaultHandler.
Public Members
virtual bool attributeDecl ( const QString & eName, const QString &
aName, const QString & type, const QString & valueDefault, const
QString & value ) = 0
virtual bool internalEntityDecl ( const QString & name, const QString &
value ) = 0
virtual bool externalEntityDecl ( const QString & name, const QString &
publicId, const QString & systemId ) = 0
virtual QString errorString () = 0
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 DOCUMENTATIONbool 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.
