[xsd-users] Help me: Borland C++ Builder 2007 compiled program has unwanted prefix and all property values are missing.

[James Mei]

Hi Boris

It seems like the serialization is trying to print out properties that
stored in the class. But the properties are stored in unicode, that is why
they are all missing in the output file.

May I know if there is any flag setting to enable that ?

e.g.

    ofstream outfile(argv[2], ios::out);
    SCL_(outfile, *h, f);
//the value for "f" ?

Or there is other API to store the xml file into the file system ?

Cheers
James
