.SH DESCRIPTION
The QXmlErrorHandler class provides an interface to report errors in XML data.
.PP
If the application is interested in reporting errors to the user or any other customized error handling, you should subclass this class.
.PP
You can set the error handler with QXmlReader::setErrorHandler().
.PP
Errors can be reported using warning(), error() and fatalError(), with the error text being reported with errorString().

.SH MEMBER FUNCTION DOCUMENTATION
.SH "bool QXmlErrorHandler::error ( const QXmlParseException & exception )\fC [pure virtual]\fR"
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 \fIexception\fR.
.PP
The reader must continue to provide normal parsing events after invoking this function.
.PP
If this function returns FALSE the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.
.SH "QString QXmlErrorHandler::errorString ()\fC [pure virtual]\fR"
The reader calls this function to get an error string if any of the handler functions returns FALSE.
.SH "bool QXmlErrorHandler::fatalError ( const QXmlParseException & exception )\fC [pure virtual]\fR"
A reader must use this function to report a non-recoverable error. Details of the error are stored in \fIexception\fR.
.PP
If this function returns TRUE the reader might try to go on parsing and reporting further errors; but no regular parsing events are reported.
.SH "bool QXmlErrorHandler::warning ( const QXmlParseException & exception )\fC [pure virtual]\fR"
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 \fIexception\fR.
.PP
If this function returns FALSE the reader stops parsing and
reports an error. The reader uses the function errorString() to
get the error message.
