[Sab] Message Handler

[Frank Vene]

Hi,

I need to log error that occurs while parsing or transforming XML content.
I use the default message handler (see example below), but sometimes I got some strange messages.

    int retCode;
    retCode = SablotRunProcessor(...);

    if( 0 != retCode ) { // an error occurred

        cerr << SablotGetMsgText(retCode) << endl;

    }

So, I think I need to implement a message handler to handle my own
messages.
I try to implement a message handler looking at the shandler and sablot
header files but I cannot achieve it.
Has someone developped a message handler? Could you send me an example?
Thanks in advance,
Frank.
