RE: problem in DOMPrint.cpp

[Da...@lotus.com]

You cannot create an instance of the class ostream -- it's an abstraction
of an output "stream."  You need an instance of a class _derived_ from
ostream.  One possible choice is std::cout, but there are many others.

Please do yourself a favor and get a good book on C++, as this question has
nothing to do with Xerces-C.

okay

i am  executing following code in main() :

           DOM_node node  = parser.getDocument();
           ostream os;
           os << node;


but even that is not working and gives following error message:

     error C2248: 'ostream::ostream' : cannot access protected member
declared in class 'ostream'
     see declaration of 'ostream::ostream'

Ehh? cout << os?

Print an ostream on stdout? Is that really what you wanna do? ;)

I think you were aiming at just:

os << node;

I know you can go totally blind when debugging your own code.

Hi,

I am trying to run the DOMPrint.cpp  sample for generating XML from DOM
tree. this sample declares and defines

three following functions for this purpose:

ostream& operator<<(ostream& target, const DOMString& toWrite);
XMLFormatter& operator<< (XMLFormatter& strm, const DOMString& s);

and

ostream& operator<<(ostream& target, DOM_Node& toWrite);  // this function
writes DOMtree data into xml format in ostream.



in my main function i am calling above as follows  :


              DOM_Node node = parser->getDocument();
               ostream os ;
                cout << os << node;



but when i compile above code,  i  get following error msg :


      error C2248: 'ostream::ostream' : cannot access protected member
declared in class 'ostream'
       see declaration of 'ostream::ostream'


could some pls tell why its happening and what i sohlud do to solve this
porblem ??
what is the correct way to call the above function in main() ??


thanks
