Hey, I want to serialize an object to xml with delphi 7, i searched but i didn't find a full solution, i think with HttpRio we can do it. Thank you in advance.

I had one problem with deserialisation. I had this: TPart1 = Class public field1: string; end; TPart = Class public part1: TPart1; end; I serialize and deserailize: all work fine. But now I want to add TPart2 to TPart like this: TPart1 = Class public field1: string; end; TPart2 = Class public field2: string; end; TPart = Class public part1: TPart1; part2: TPart2; end; And I’d like to deserialize from TPart XML who was serialized with old TPart (only TPart1) and it fail. Is there a way to make this?

JVCL is one choice, but if you prefer a small, self-contained library, there's OmniXML (Mozilla Public License 1.1, ). I've used it successfully in several projects, and I find it the simplest XML library to use in Delphi. OmniXML comes with 'OmniXMLPersistent' unit, which does what you need via RTTI, just like the JVCL solution does. // saving: pers: TPersistent; // SaveToFile is a class method, so no need to instantiate the object: TOmniXMLWriter.SaveToFile( pers, 'd: path file.xml', pfAttributes, ofIndent ); pfAttributes means properties will be stored as attributes of XML elements; ofIndent will produce a nicely indented code for readability. // loading: TOmniXMLWriter.LoadFromFile( pers, 'd: path file.xml' ).
