[SOLVED] QRegExp help needed

[kalster]

I am having problems with the QRegExp in my client / server app. the following is what i currently have and it works good.
@// Normal messges look like this: "username:The message"
QRegExp messageRegex("^([^:]+):(.*)$");
QString user = messageRegex.cap(1);
QString message = messageRegex.cap(2);@

in the above code, it brakes up the "username", and "The message" into two variables. the problem is that i need to add another variable to the list for the private chat. i would like it to be the following but it is not working. i am getting a bad message error.

@// Normal messges look like this: "username:tabName#The message"
QRegExp messageRegex("^([^:]+):([^#]+)#(.*)$");@

in the client, I am trying to brake "username", "tabName" and "The message" into three different variables.

in the following code it reads from the client. if the message = -1 then give the error...

    @QString line = QString::fromUtf8(client->readLine()).trimmed();
    QRegExp meRegex("^/me:(.*)$");
    if(meRegex.indexIn(line) != -1)
    {
        user = meRegex.cap(1);
        users[client] = user;
    }
    else if(users.contains(client))
    {
        QString message = line;
        user = users[client];
    }
    else
    {
        emit display("Got bad message from client:" + client->peerAddress().toString() + line);
    }
}@

Don't underestimate the power of a simple, real parser over regular expressions. These are often a very good way of getting things done and done even quicker than with RegExes.

can i have a link to the parser docs please :)

Not a docs... Just use regular QString functions for finding ":" and sub-stringing.

thank you veeeee_d. i have also decided later after your first post that QString functions are the best for what i need to do. :). this topic is solved.
