The DOM does not work with tags, it works with nodes, you can create a 
new table element node for instance, and insert that somewhere as a 
children of another node. You can also create and insert new nodes as 
children of the table element node. Or you can move existing nodes.

It is not clear what you want as the result but here is a simple example 
in C#

     string xmlMarkup = @"<span>
<div  align=""center"">
<input id=""myTxt"" type=""text""
style=""background-color:LightSteelBlue;width:90%"" autosuggest=""true"" />
  <input type=""button"" value=""myButton"" onclick=""myFunction();"" />
</div>
</span>";
     XmlDocument xmlDocument = new XmlDocument();
     xmlDocument.LoadXml(xmlMarkup);

     XmlNode inputElement = 
xmlDocument.SelectSingleNode(@"/span/div/input[@type = 'text']");
     if (inputElement != null) {
       XmlElement tableElement = xmlDocument.CreateElement("table");
       XmlElement tbodyElement = xmlDocument.CreateElement("tbody");
       tableElement.AppendChild(tbodyElement);
       XmlElement trElement = xmlDocument.CreateElement("tr");
       tbodyElement.AppendChild(trElement);
       XmlElement tdElement = xmlDocument.CreateElement("td");
       trElement.AppendChild(tdElement);
       inputElement.ParentNode.InsertBefore(tableElement, inputElement);
       tdElement.AppendChild(inputElement);
     }
     xmlDocument.Save(Console.Out);

The resulting serialized XML is then

<?xml version="1.0" encoding="utf-8"?>
<span>
   <div align="center">
     <table>
       <tbody>
         <tr>
           <td>
             <input id="myTxt" type="text" 
style="background-color:LightSteelBlue;width:90%" autosuggest="true" />
           </td>
         </tr>
       </tbody>
     </table>
     <input type="button" value="myButton" onclick="myFunction();" />
   </div>
</span>
