Solution 1

There are a couple of ways to do it - you could use a loop and the string.Substring method, or (possibly) a regex - but the last would probably want a loop or Linq method to "rebuild" the string with the "*" prefix.
The loop option is pretty simple:
Use string.IndexOf to find the "*" character.
Use a for loop, starting at the character after the star, ending at the string length, incrementing by three each time.
In the loop, use string.Substring to extract the three characters, and add them to a List of strings, together with the "*" prefix.

Solution 2

XML

XmlDocument xmlDoc = new XmlDocument();
       xmlDoc.Load(@"D:\Prod.xml");

      XmlNode node = xmlDoc.DocumentElement.FirstChild;
      XmlNodeList lstVideos = node.ChildNodes;
      for (int i = 0; i < lstVideos.Count; i++)
       {
         
           for (int j = 0; j < 3; j++)
           {
               Response.Write("  " + lstVideos[j].InnerText + " ");
           }
           Response.Write("<br>");
       }

xml file is:

XML

<?xml version="1.0"?>
-<DocumentElement>
-<test>
<c0>manas</c0>
