How to deal with unkown char array data



  • When reading data into my char buffer 4096 from QTcpSocket, sometimes the data looks like:

    Format 1:
    <\000?\000x\000m\000l\000 \000v\000e\000r\000s\000i\000o\000n\000=\000"\0001\000.\0000\000"\000 \00

    and sometimes the data looks like:

    Format 2:
    <?xml version="1.0" encoding="utf-16"?>\r\n<data version="1.0">\r\n <routing>\r\n

    How can I consistently convert the buffer data into a QString?

    QString myString(buffer); works for Format 2, but not for Format 1 and

    QString myString = QString::fromRawData((char*)buffer, bytesReceived) works for Format 1, but not for Format2.

    Thanks.



    1. You need to analyze the incoming data and then select correct QString creation procedure.
      or
    2. A data source server should send some flag to identify what kind of format will be used for next message.
