Hi Nye,
In fact, my regular expression was wrong. Yours works like a charm. I appreciate your help. Thank you so much 😊

Hello,
Your regular expression is very strange. You have a character class with two symbols and then you don't have a capture group? Maybe try this: "(?<=\\s)c:\\s?(.*)$"
Kind regards.

I am currently trying to extract the following chain of character:
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 ?
Best regards
David
