Answer 1

By using XDocument

 var doc = XDocument.Parse("your xml string");
   //namespace
   var nspace = doc.Root.Name.Namespace;
    foreach (var item in doc.Descendants(nspace+"DataSet"))
    {

        var str = new StringBuilder();
        var str1 = new StringBuilder();
        str.Append("<Field Name='CommunicationDataValueId'>");
        str.Append("<DataField>CommunicationDataValueId</DataField>");
        str.Append("<TypeName>System.Int64</TypeName>");
        str.Append("</Field>");
        str1.Append("<Field Name='DeviceMasterId'>");
        str1.Append("<DataField>DeviceMasterId</DataField>");
        str1.Append("<TypeName>System.Int32</TypeName>");
        str1.Append("</Field>");
        item.Add(XElement.Parse(str.ToString()));
        item.Add(XElement.Parse(str1.ToString()));
    }

Answer 2

Take a look at the following API for XElement - AddAfterSelf.

You can find each relevant Query element and call that method, adding the piece of XML you want to add.
