Adding an element at each parent node at a specific position

[jangirdimple90]

I need to add element "REFERENCE" for every parent node after STATUS element.
<ORDER> <DETAIL> <STATUS>1</STATUS> <TYPE>1</TYPE> </DETAIL> <DETAIL> <STATUS>2</STATUS> <TYPE>3</TYPE> </DETAIL> </ORDER>

System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
            doc.Load(filename);
 
            //Specify root where the new element needs to added
            System.Xml.XmlNodeList WHORDER = doc.SelectNodes("//ORDER/DETAIL");
            System.Xml.XmlNode STATUS = doc.SelectSingleNode("/ORDER/DETAIL/STATUS");
 
            if (STATUS != null)
            {                
                foreach (System.Xml.XmlNode item in WHORDER)
                {
                    System.Xml.XmlElement REFERENCE = doc.CreateElement("REF");
                    REFERENCE.InnerText = 'A';
 
                    System.Xml.XmlNode commonParent = STATUS.ParentNode;
                    commonParent.InsertAfter(REFERENCE, STATUS);                   
                }
            }
 

the output looks like
<ORDER> <DETAIL> <STATUS>1</STATUS> <REF>A</REF> <REF>A</REF> <TYPE>1</TYPE> </DETAIL> <DETAIL> <STATUS>2</STATUS> <TYPE>3</TYPE> </DETAIL> </ORDER>

Can anyone help me with what am i doing wrong?
