Extract a complete sentence using a QRegularExpression

Question

I am currently trying to extract the following sentence:

This is a rectangle. Its height is 193, its width is 193 and the word number is 12.

from the following line:

ID: 1 x: 1232 y: 2208 w: 193 h: 390 wn: 12 ln: 13 c: This is a rectangle. Its height is 193, its width is 193 and the word number is 12 !

I have to do this using QRegularExpressions. Therefore, my code is as following:

regularExpression.setPattern("[c:](?:\\s*)$");
QRegularExpressionMatch match = regularExpression.match("ID: 2 x: 845 y: 1633 w: 422 h: 491 wn: 78 ln: 12 c: qsdfgh");
if (match.hasMatch()) {
    QString id = match.captured(0);
    qDebug()<<"The annotation is:"<<id;
    return id;
}
return 0;

However, it does not work at all and I do not understand why (maybe my regular expression is not correct).I am stuck in this problem from several days now.

Could you help me please ?

Hi Frank, I have to do it using QRegularExpressions because I am actually using Qt. — Dave_Dev, Dec 27 '15 at 22:50
Not sure if QRegularExp.. works differently but how about this? regularExpression.setPattern("c:\s*(.*$)"); — Simo Erkinheimo, Dec 27 '15 at 22:52
Hi Simo. It works like a charm. I appreciate your help. Thank you so much :) — Dave_Dev, Dec 27 '15 at 22:56
If that was the answer, please add it as such one. /cc @SimoErkinheimo — hakre, Dec 27 '15 at 23:13

Use following regex to parse everything after c: and to also remove possible white space from the beginning of the string:

regularExpression.setPattern("c:\s*(.*$)");
