Hello David,
No problem. QRegularExpression is PCRE (perl-compatible reg ex) so you could
use https://regex101.com with (php-pcre on the left) to check your patterns
against a sample string, and even you get an explanation on the right what is
done/matched. Not everything (as syntax) is supported in Qt, but most of the
things are available.
Kind regards,
Konstantin.

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
