if we supposed that "A.B." is a value for an xml element called given-names the following code converts this value to "A.tempspacetempspaceB." instead of "A. B."

foreach (XElement initial in doc.XPathSelectElements("//given-names"))
                                {
                                    string v = initial.Value.Replace(".", ". ").TrimEnd(' ');
                                    initial.SetValue(v);
                                }

So why tempspace comes here instead of literal space??

thank you for any help.
