Hi Stephan

You'd want to get hold of the repeating group node, clone it, change the
values, then add it after the original node.

Something along these lines

XPathNavigator repeatingNode =
MainDataSource.CreateNavigator().SelectSingleNode("/my:Example/my:RepeatingNode",
NamespaceManager);
for(int i=1;i<=10;i++)

{

XPathNavigator newNode = repeatingNode.Clone();

newNode.SelectSingleNode("/my:Example/my:RepeatingNode/my:ID",
this.NamespaceManager).SetValue(i.ToString());

newNode.SelectSingleNode/my:Example/my:RepeatingNode/my:Name",
this.NamespaceManager).SetValue("Example " + i.ToString());

try

{

repeatingNode.InsertAfter(newNode);

}

catch (Exception)

{

}

}

repeatingNode.DeleteSelf();

Hope this helps
Andy
