You can use one of the serialization functions together with
std::ostringstream. For instance, in the library example there is
the this line:
// Write it out.
catalog_ (std::cout, *c, map);
You can replace it with something like this (also add #include <sstream>):
// Write it to string.
catalog_ (ostr, *c, map);
std::string str = ostr.str (); // XML is in str.
In my xsd definition and compliation (i did use the --generate-serialization per yr note in the example), I don't find the catalog_ definitions/declarations. (I get an catalog_ undeclared compile error). In order to use route 1, is it a must to create a document object in the XSD definition like how you did it in library example?
(xsd:element name="catalog" type="lib:catalog"/>)
If so, What if you don't have a documentation declaration in xsd (I have many xsd definitions and would like to avoid creating document objects for each one of them).

There is some sample DOM manipulation code on the Wiki, see for example
3.1 and 3.2:
The ostringstream way is much easier though.
>> True, ostringstream is definitely the right approach but am wondering if I need to do something different w/ my xsd definitions...
