Question

What’s a good way to serialize a Delphi object tree to XML–using RTTI and not custom code?

I would have loved to find that this feature is already built into Delphi, but it doesn’t seem to be.

I’ve found a few components (posted, below) that seem like they might perform this function. Have you used any of them or some other offering? Have you built your own? Am I missing something obvious, in Delphi?

You can use the JVCL TJvAppXMLFileStorage component to serialize TPersistent derived classes.

uses   JvAppXMLStorage;  var   Storage: TJvAppXMLFileStorage; begin   Storage := TJvAppXMLFileStorage.Create(nil);   try     Storage.WritePersistent('', MyObject);     Storage.Xml.SaveToFile('S:\TestFiles\Test.xml');      Storage.Xml.LoadFromFile('S:\TestFiles\Test.xml');     Storage.ReadPersistent('', MyObject);   finally     Storage.Free;   end; end;
