One of the elements in the DTD is a list (FLAG_99*..<!ELEMENT FLAG_99 (#PCDATA)>), in most cases this list is empty. When I save the generated XML to a file there is no <FLAG_99> node to indicate the empty list. The system on the receiving end needs this node, how can I force delphi to generate it ?. eg. : XMLData : String; tmpX : IXMLMyType; : : tmpX := NewMyType; // Function generated by wizard returning IXMLMyType (derived from IXMLNode) : : tmpX.something.add.property := 'xxx'; : XMLData := tmpX.XML; // No <FLAG_99> node present if I've never done tmpX.FLAG_99.Add('yyy'); Thanks for any ideas Ian Healy.

For example you can write tmpX.FLAG_99.Count ad you will have your empty tag, or bettere add an empty alement and remove it, for example tmpX.FLAG_99.Add(''); tmpX.FLAG_99.Delete(0); // or remove i don't remember Bye "Ian Healy" <I.healy (AT) grupposisge (DOT) it> ha scritto nel messaggio news:43c53120 (AT) newsgroups (DOT) borland.com...
