QuestionRegular expression error ? Pin
Salvatore Terress21-Oct-23 7:42
Salvatore Terress21-Oct-23 7:42 
I am trying to extract MAC address from text, and it is failing.

Here is the debug print of the "inString" text to extract the MAC from :

"Inquiring ...\n\t98:D3:31:F8:39:33\tclock offset: 0x7c6b\tclass: 0x001f00\n"


Here is my temporary code with regular expression which must be in error, but I do not see it.


QRegularExpression re(" [^\x00-\x7F]+\\ *(?:[^\x00-\x7F]| )*");
        QRegularExpressionMatch match = re.match(inString);


         if (match.hasMatch()) {
            text = " Has match ";
            QStringList result = match.capturedTexts();
            text += result.at(0);    // test show only first

         }
         else
         {
            text = " NO match found ";
         }

 qDebug() << text;



Here is "run time error " , I am not sure why " invalid object" .

Does it mean my regular expression is incorrect ?

QRegularExpressionPrivate::doMatch(): called on an invalid QRegularExpression object
" NO match found "


If additional info would help, please ask.

Help analyzing the expression would be also greatly appreciated.

Thanks
