1) Your XML input file is not quite ok

Use this:

www.abc.com" enable="Yes" />
www.abc1.com" enable="Yes" />

2) Your C# code has some bugs.
When calling SelectSingleNode for example you shouldn't start the XPath
string with / (forward slash) ... Remove that slash.
Just start with the name of the sub-node.

You can compare your code with this code:

using System;

using System.Xml;

using System.IO;

namespace TestXML

{

class MainProg

{

[STAThread]

static void Main(string[] args)

{

XmlDataDocument xmlDoc = new XmlDataDocument();

string dataFile = "test_input.xml";

string cboURLName = "abc";

xmlDoc.Load(dataFile);

XmlNodeList list = xmlDoc.GetElementsByTagName("data");

foreach(XmlNode node in list)

{

Console.WriteLine("/data/website[name='" + cboURLName + "']");

node.RemoveChild(node.SelectSingleNode("website[@name='" + cboURLName + "']"));

}

xmlDoc.Save(new System.IO.FileStream( "test_output.xml", FileMode.Append, FileAccess.Write) );

}

}

}

3) Make sure you have the test_input.xml file in the folder where your EXE is before you run the EXE.

Then check the output file test_output.xml which will be created by the program when you start it.

I am getting an error..
"Object reference not set to an instance of an object."

XmlDataDocument xmlDoc = new XmlDataDocument();

xmlDoc.Load(dataFile);

foreach(XmlNode node in xmlDoc.GetElementsByTagName("website"))

{

node.RemoveChild(node.SelectSingleNode("/website[@name='" + this.cboURLName.Text + "']"));

Console.WriteLine("/data/website[name='" + this.cboURLName.Text + "']");

}
