Problem with using RegExp

[Subuday]

I need to determine /hello.htm in string GET /hello.htm HTTP/1.1 User-Agent: Mozilla/4.0 \r\n using RegExp. I use

\/.+?\s

It wokrs fine on Online Regular Expression
but in qt it doesn't

    QRegExp uriRegExp("\/.+?\s");
    int lastPos  = 0; 
           
     while((lastPos = uriRegExp.indexIn(myString, lastPos)) != -1)
    {
       qDebug() << uriRegExp.cap(1);
       lastPos += uriRegExp.matchedLength();
  }

@Subuday Change

QRegExp uriRegExp("\/.+?\s");

to

QRegExp uriRegExp("\\/.+?\s");

@jsulm Doesn't work

qDebug() << "Starting";
QString testString("GET /hello.htm HTTP/1.1 User-Agent: Mozilla/4.0 \r\n ");
QRegularExpression re("/.+?\\s");
QRegularExpressionMatch match = re.match(testString);

if (match.hasMatch())
{
    QString matched = match.captured(0);
    qDebug() << "Matched " << matched;
}
else
{
    qDebug() << "No match";
}

qDebug() << "done";

@Subuday Should be

QRegExp uriRegExp("\\/.+?\\s");

\ is escape character in C++, if you want to use it as part of a string you have to escape it as \\
