{{Quickfixn}} fix 4.4 - iterate on tags

[Oscar Porta]

Hi
sorry to bother you with a silly question but I didn't understand yet how
to solve this simple problem.
I have a FIX message in form of a string which I use to initialize aan
object FIX::Message.
I would like to iterate on the FIX tags in the order they appear in the
string.
The following is an extract of my code. Unfortunately the loop on the
iterator returns the tags in "alphabetical order.
Do you have any suggestion for my problem?
Thanks in advance.
Regards,
Oscar Porta


// -------------------------
void myFunc(char *inMsg)
{
    FIX::Message *fm = new FIX::Message(inMsg);

    // this iterates in "alphabetical" order
    for (FIX::Message::iterator it=fm->begin(); it!=fm->end(); it++)
    {
        FIX::FieldBase f = it->second;
        int i = it->first;
        std::string v = f.getString();
        printf("%d %s\n", i, v.c_str());
    }
}

with this input message
