QRegularExpressionMatch A:B/C to A,B,C

A:B/C to A,B,C

QString location = "192.168.2.101:1068/description.xml";
QRegularExpression RE("(:*)(/*)");
QRegularExpressionMatch REM = RE.match(location);
QString IP = REM.captured(0);
QString port = REM.captured(1);
QString description = REM.captured(2);

IP = "192.168.2.101"
port = "1068"
description = "description.xml"

@sonichy Why is regex necessary? I see that it is enough to use QString::split() 2 times: the first with ":" and the second with "/".

@sonichy
You could do it in two statements as @eyllanesc wrote. (Though it won't cope so easily if, say, the filename part is allowed to be a path with multiple /s, which I assume it could be.) I would probably do it with a regular expression, but you want 3 captured elements and your reg ex only calls for 2. It's really very simple. I would go something like (untested):

QRegularExpression RE("([^:]*):([^/]*)/(.*)");

@JonB
"192.168.2.104:1068/description.xml"
"192.168.2.104"
"1068"

Code should change to this:

QString IP = REM.captured(1);
QString port = REM.captured(2);
QString description = REM.captured(3);

Acturally, my full line is:
LOCATION: http://192.168.2.104:1068/description.xml
How to Match ?

@sonichy
Depends what ranges of input you need to cover. For the string you show what about:

"[^/]*//([^:]*):([^/]*)/(.*)"
