Member Function Documentation

bool QXmlDeclHandler::attributeDecl ( const QString & eName, const QString & aName, const QString & type, const QString & valueDefault, const QString & value ) [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, 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 either "#IMPLIED", "#REQUIRED", "#FIXED" or null (if none of the other applies). Finally, 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 that is used for reporting the error.

QString QXmlDeclHandler::errorString () [virtual]

The reader calls this function to get an error string if any of the handler functions returns FALSE to him.

bool QXmlDeclHandler::externalEntityDecl ( const QString & name, const QString & publicId, const QString & systemId ) [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 that is used for reporting the error.

bool QXmlDeclHandler::internalEntityDecl ( const QString & name, const QString & value ) [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 that is used for reporting the error.
