for xml like
<user>
    <name>Pony</name>
    <age>20</age>
</user>

Just define such a structure
struct User {
    string name;
    int age;
    XPACK(O(name, age));
};

!!!!NO NEED!!! to define:
struct Data {
    User user;
    XPACK(O(user));
};

xml::decode will skip the root node, so for the xml defined above,
it only needs to be decode like this:
User u;
xpack::xml::decode(str, u);
