In the C++ API, the Message class is derived from FieldMap, which offers
public methods begin()/end() and g_begin()/g_end() to get standard iterator=
s
to the maps of fields and groups. Message also contains two additional
FieldMaps which store the Header and Trailer fields.

for (FieldMap::iterator i =3D msg.begin (), e =3D msg.end (); i !=3D e; ++i=
)
cout << i->first << '=3D' << i->second << ' ';

That should print all of the non-group fields in a message in "tag=3Dvalue"
format.

Navigation of the header fields, trailer and repeating groups is an exercis=
e
left to the reader :-)
