 Xml Serialization - Basic Usage http://robstechcorner.blogspot.com/2009/10/xml-serialization-basic-usage.html

// Method 1:
var
 o : TypeIWantToSerailze;
 s : TXmlTypeSerializer;
 x : TXmlDocument;
 v : TValue;
begin
  s := TXmlTypeSerializer.create(TypeInfo(o));
  x := TXmlDocument.Create(Self); // NEVER PASS NIL!!!
  s.Serialize(x,o);
  x.SaveToFile('FileName.txt');
  v := s.Deserialize(x);
  o := v.AsType<TypeIWantToSerailze>;
  x.free;
  s.free;
end;

// Method 2:
var
 o : TypeIWantToSerailze;
 s : TXmlSerializer<TypeIWantToSerailze>;
 x : TXmlDocument;
begin
  s := TXmlTypeSerializer<TypeIWantToSerailze>.create;
  x := TXmlDocument.Create(Self); // NEVER PASS NIL!!!
  s.Serialize(x,o);
  x.SaveToFile('FileName.txt');
  o := s.Deserialize(x);
  x.free;
  s.free;
end;

The extended RTTI works like Reflection in .NET. It gives you access to your internal application structure information. You can access class properties, methods etc.. at runtime, at extent you could not do it before.

Some ways of using it:

    Serialization / Deserialization of classes to XML or other media
    Mapping of objects to databases. ORM.
    Cloning of objects
    Dynamic invocation of methods
    "Scanning" of object at runtime and acting according to that.
    Easier development of "plugin" type systems

There is probably a lot of scenarios where it would be beneficial to use it. In short it adds dynamic aspect to your application. Your product is able to do some things at runtime, and more efficiently, than designing everything at designtime. It is not a silver bullet and a lot of people may never use it. But some design patterns or some problems just cannot be solved (at least not in efficient way) without the use of the new RTTI
