Delphi7.0 向XML中添加RTTI信息,这个例子挺简单,希望大家喜欢,面向Delphi新手的,高手请绕道哦,下面是本例Delphi向XML中添加RTTI信息的关键性代码:
procedure TForm1.ComponentToDOM(iNode: IXmlNode; Comp: TPersistent);
var
nProps, i: Integer;
PropList: PPropList;
Value: Variant;
newNode: IXmlNode;
begin
nProps := GetTypeData (Comp.ClassInfo)^.PropCount;
GetMem (PropList, nProps * SizeOf(Pointer));
try
GetPropInfos (Comp.ClassInfo, PropList);
for i := 0 to nProps - 1 do
begin
Value := GetPropValue (Comp, PropList [i].Name);
NewNode := iNode.AddChild(PropList [i].Name);
NewNode.Text := Value;
if (PropList [i].PropType^.Kind = tkClass) and (Value 0) then
if TObject (Integer(Value)) is TComponent then
NewNode.Text := TComponent (Integer(Value)).Name
else
ComponentToDOM (newNode, TObject (Integer(Value)) as TPersistent);
end;
finally
FreeMem (PropList);
end;
end;
