...... and so on

now i am reading the contents of the datum number(n) and X Y Z values using QRegExp but if try to read i am getting ASSERT problem please help us here is my code and error msg

void DatumForm::readfile()
{


QString result;
QFile file( "datum.txt" );
if ( file.open( IO_ReadOnly ) ) {
QTextStream stream( &file );
QString line;
int linenumber = 0;
while ( !stream.atEnd() ) {
line = stream.readLine();
QRegExp rx ( "^\\d\\d?$" );
rx.search ( "Datumno_Val" );
result = rx.cap ( 0 );
resulttemp = result;
printf( "%3d: %s\n", linenumber++, line.latin1() );
//lines += line;

}

file.close();
}
}

void DatumForm::init()
{
Datumno_Val = DatumVal;
datumnolineEdit->setFocus();
decimals_mm_datum = 3;
readfile();

QStringList lines = QStringList::split( FIELD_SEP, resulttemp );
Datumno_Val = lines[0].toInt();
qDebug ( "Datum number : %d",Datumno_Val);
Xdatum_Val = lines[1].toDouble();
xdatcountlineEdit->setText(QString::number( Xdatum_Val, 'f', decimals_mm_datum) );
qDebug ( "Xdatum_Val : %4.3lf",Xdatum_Val);
Ydatum_Val = lines[1].toDouble();
qDebug ( "Ydatum_Val : %4.3lf",Ydatum_Val);
Zdatum_Val = lines[1].toDouble();
qDebug ( "Zdatum_Val : %4.3lf",Zdatum_Val);

}
