Thanks. In the future please refrain from sending generated code and
executables -- XML file, schema file and your implementation are usually
enough.

It does not work because you parser structure does not correspond to
the document structure. For example, you are trying to parse a root
element of the document with the header_infoType parser.

Here is a working parser for the root element to get you started:

struct cartconf_parser: cartconf<void,
                                 string, //cart_conf_version
                                 void,
                                 void,
                                 void,
                                 void>

{

  virtual void
  cart_conf_version (const string& v)
  {
    cout << "version: " << v << endl;
  }
};


xml_schema::string string_p;
cartconf_parser cartconf_p;

cartconf_p.cart_conf_version_parser (string_p);
xml_schema::document<void> doc_p (cartconf_p, "cartconf");


Now in order to get to the name and revision, you will first need to
implement a parser for cart_header and plug it into cartconf after the
version. Only then you can get to the header_infoType parser which
should be plugged to the cart_header parser.
