Since I have no idea what you HTML looks like I am completely shooting in the dark. Try to use the HTML Agility pack to grab the specific nodes you want for easier extrapolation of nodes. Also, your example is obviously in some other nodes that you are not showing. Your text is not in anything meaningful:

<name>
    <a href="www.msdn.com">msdn link</a>
    hi test text <test>dsgfdsh<test>                               <--see what I mean
    <a name="test" href="www.msdn.com">msdn2 link</a>
</name>

Any who, I just did a basic replace:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            String additional = "~%msdn link^www.msdn.com%~";
            String anchor = @"<a href=""www.msdn.com"">msdn link</a> hi test text <test>dsgfdsh<test><a name=""test"" href=""www.msdn.com"">msdn2 link</a>";

            anchor = anchor.Replace("hi", additional + " hi");
            anchor = anchor.Replace("<test><a", "<test>" + additional + "<a");
        }
    }
}

//~%msdn link^www.msdn.com%~ hi test text <test>dsgfdsh<test> ~%msdn2 link^www.msdn.com%~

If I had more information and more HTML, it would be helpful. As I am not sure if you are just giving me values that you already pulled out.

Hi,

For example there is an html text which consists of anchor tag as shown below

<b>test</b><a href="www.msdn.com">click here</a><li>test list</li>

I want to replace only anchor tag in below format,

<b>test</b>~#click here^www.msdn.com#~<li>test list</li>

Hi Gopi,

Welcome to the MSDN Forum.

Please try this code:

anchor = Regex.Replace(anchor,@"<a.*?href=""(?<link>.*?)"">(?<content>.*?)</a>",@"~#${content}^${link}#~")

I hope this will be helpful.

Best regards,
