Reading node values from xml

I have an XML File and the format is

<?xml version="1.0" encoding="utf-8"?>
<ROWDATA>
<ROW ORGCODE="00001" BRANCHCODE="00002"/>
<ROW ORGCODE="00001" BRANCHCODE="00003"/>
<ROW ORGCODE="00001" BRANCHCODE="00004"/>
<<ROW ORGCODE="00001" BRANCHCODE="00005"/>
</ROWDATA>

while reading the xml , only 1st and 3rd node (ORGCODE="00001" ,BRANCHCODE="00002" and ORGCODE="00001",BRANCHCODE="00004") are fetching.Need to read every node

My code structure is

 using (StreamReader oReader = new StreamReader(FileName, Encoding.GetEncoding("ISO-8859-1"))) 
     {        
            int i = 0;
            int j = 0;
                    XmlReaderSettings xrs = new XmlReaderSettings();
                    xrs.CheckCharacters = false;
                    xrs.ConformanceLevel = ConformanceLevel.Document;

                    using (XmlReader reader = XmlReader.Create(oReader, xrs))
                    {
                        while (reader.Read())
                        {
                            switch (reader.NodeType)
                            {
                                case XmlNodeType.Element:
                                    switch (reader.LocalName.ToUpper())
                                    {
                                        case "ROW":
                                            //Insert details to database
                                            if (retval == "100")
                                            {
                                                i++;
                                            }
                                            j++;
                                            obj = null;
                                            break;
                                    }
                                    break;
                            }
                        }
                    }
                }
