This is my sample code in which I repeat the <LinkURl> and <LinkText> field.
but I have to now repeat whole <SupportItems> tags
How can I did this pls any one can response me. I will very thankful for that.

This is my sample code


if (strAlbumName != "" && strAlbumPath != "")
            {
                strXMLFile = strAlbumPath + "\\" + strAlbumName + ".linkinfo.xml";
                XmlDocument doc = new XmlDocument();
                doc.Load(strXMLFile);

                System.Data.DataSet objDataSet = new DataSet();

                FileStream findata = new FileStream(strXMLFile, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
                objDataSet.ReadXml(findata);
                findata.Close();
                //int intRefId = Convert.ToInt32(Request.QueryString["RefId"]);
                int intRefId = 3;
                string strFilePath = FileUpload.PostedFile.FileName;
                string strXPath = "/LinkInformation/ScreensToSupport/ScreenToSupport/SupportItems/ScreenSupportItem[RefId='" + intRefId + "']";

                XmlNode newParent = doc.SelectSingleNode(strXPath);

                foreach (System.Xml.XmlNode node in newParent)
                {
                    if (node.Name == "LinkURL")
                    {
                        if (node.InnerText == FileUpload.PostedFile.FileName)
                        {
                            BaydonConstants.flag = true;
                            break;
                        }
                    }
                    else if (node.Name == "LinkText")
                    {
                        if (node.InnerText == txtUrlTitle.Text)
                        {
                            BaydonConstants.flag = true;
                            break;
                        }
                    }
                }
                if (BaydonConstants.flag)
                {
                    lblError.Text = "LinkURL/LinkText already exist !";
                    BaydonConstants.flag = false;

            }
        }

To create a copy of a node you can use the XmlNode.Clone() method to create the copy.

Hello sir I have tried it but its not working according to my requirement. I have to create a new child <ScreenSupportItem> below the parent node <SupportItems> with matching condition --where attribute of <ScreenSupportItem> e.g <RefId> is equal to 3 (comes from query string). Also new <ScreenSupportItem> child have different attributes except <RefId>. So I have to create a <ScreenSupportItem> with setting new values of all the attributes.

It giving error 'ERROR:Cannot insert a node or any ancestor of that node as a child of itself.'
I am very new in xml please help me to solved my problem. I will very thankful for your valuable cooporation.
Please reply me soon....

Well for starters you've got the parameters the wrong way around for the InsertAfter method. Personally I'd just use the AppendChild method.

XmlNode newScreenToSupport = newParent.Clone();
newParent.ParentNode.AppendChild(newScreenToSuppor t);

Hello sir

There is a little problem of xml again.
How can I go through all child nodes and attributes of child nodes of a parent node..

Suppose i have to go through all child nodes e.g.<ScreenSupportItem> of parent nodes e.g.<SupportItems>. There can be mutiple <ScreenSupportItem> in a parent node <SupportItems>. I have to check values of <LinkURL> and <LinkText> of all child nodes <ScreenSupportItem> and if it matches with the supplied valus it gives a message 'LinkUrl/LinkText already exist' else insert new <ScreenSupportItem> of <ScreenSupportItem> and set all attributes of <ScreenSupportItem> , which was supplied by the user.
My code check only first child <ScreenSupportItem> of <SupportItems> if it values matches for <LinkURL> and <LinkText> give a proper message else insert new <ScreenSupportItem>.
So how can I check all child <ScreenSupportItem> for values <LinkURL> and <LinkText> of <SupportItems>

Please don't ask the same question in two places - it then forces people to take twice as long to work out what you want.
