Detailed Description

The QXmlErrorHandler class provides an interface to report errors in XML data.

Note

This class or function is reentrant.

Attention

Module: QtXml

If you want your application to report errors to the user or to perform customized error handling, you should subclass this class.

You can set the error handler with QXmlReader::setErrorHandler().

Errors can be reported using warning(), error() and fatalError(), with the error text being reported with errorString().

Functions

error()

bool QXmlErrorHandler::error ( const QXmlParseException &  exception )

pure virtual

A reader might use this function to report a recoverable error.

A recoverable error corresponds to the definiton of "error" in section 1.2 of the XML 1.0 specification. Details of the error are stored in exception.

The reader must continue to provide normal parsing events after invoking this function.

If this function returns false the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.

Implemented in QXmlDefaultHandler.

errorString()

QString QXmlErrorHandler::errorString ( ) const

pure virtual

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

Implemented in QXmlDefaultHandler.

fatalError()

bool QXmlErrorHandler::fatalError ( const QXmlParseException &  exception )

pure virtual

A reader must use this function to report a non-recoverable error.

Details of the error are stored in exception.

If this function returns true the reader might try to go on parsing and reporting further errors, but no regular parsing events are reported.

Implemented in QDomHandler, and QXmlDefaultHandler.

Referenced by QXmlSimpleReaderPrivate::reportParseError().

warning()

bool QXmlErrorHandler::warning ( const QXmlParseException &  exception )

pure virtual

A reader might use this function to report a warning.

Warnings are conditions that are not errors or fatal errors as defined by the XML 1.0 specification. Details of the warning are stored in exception.

If this function returns false the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.

Implemented in QXmlDefaultHandler.
