Hi All,

I want to read below xml data.

<MetaDataVersion OID="CDASH_MetaDataVersion_2011-10-24" Name="CDASH MDV">
<FormDef OID="F.AE_2011-10-24" Name="Adverse Event" Repeating="No">
<ItemGroupRef Mandatory="Yes" ItemGroupOID="IG.AEYN_2011-10-24"/>
<ItemGroupRef Mandatory="Yes" ItemGroupOID="IG.AE_DETAILS_2011-10-24"/>


IF you see I want data from "FORMDef" Element and want to check if it has "ItemGroupRef" then i want to read. When I am reading using XMLTextreader, I am able to read "FormDef" but I want to read "ItemGroupRef" in same loop. If it is present then read and move reader to next element.

Now when I am reading my program goes to "FORMDef" and in next cycle it is going to "ItemGroupRef" but since "ItemGroupRef" is sub element of "FormDef" i want to read it at one go and move reader to next.

Kidly Help

What I have tried:

public ArrayList Form_data = new ArrayList();
        public struct Form_attr
        {
            public string OID;
            public string Name;
            public string repeating;
        };
        public frmMain()
        {
           
            InitializeComponent();
            load_XML();
        }

        public void load_XML()
        {
         
            Form_attr fa;
            try
            {
                XmlTextReader reader = new XmlTextReader("updated.xml");
                while (reader.Read())
                {
                    if ((reader.NodeType == XmlNodeType.Element) && (reader.Name == "FormDef"))
                    {
                        if (reader.HasAttributes)
                        {
                            fa.OID = reader.GetAttribute("OID");
                            fa.Name = reader.GetAttribute("Name");
                            fa.repeating = reader.GetAttribute("Repeating");
                            Form_data.Add(fa);
                            
                            
                        }
                                           
                        
                        
                    }
                 /*   else if ((reader.NodeType == XmlNodeType.Element) && (reader.Name == "FormDef"))*/



                }
            }
            catch (Exception e)
            {
                MessageBox.Show(e.Message);
            }
            finally
            {
               
            }


            for (int i = 0; i < Form_data.Count; i++)
            {
                Form_attr test = (Form_attr)Form_data[i];
              Console.WriteLine("Form OID--> "+test.OID+" Name==>"+test.Name+"   Repeating-->"+test.repeating );
            }
            
        }
    }
}
