You can access all the result by using some thing from this

IList<XFormData> data = Xform.GetPostedData(ActivePage.PageGuid, DateTime.MinValue, DateTime.MaxValue);
                List<XFormData> only = new List<XFormData>();
                string tmp="";
                foreach (XFormData d in data)
                {
                    tmp = d.GetValue("OnlyLang");
                    if (CurrentPage.LanguageID.Equals(tmp))
                        only.Add(d);
                }
