You can use some thing like this:

XmlTextReader xmlreader = new XmlTextReader(strfilename);
xmlreader.ReadToFollowing("sometext");
xmlreader.ReadToDescendant("textundersometext");

Some thing like that ? (where xmlTest is the string containing your XML)

        XmlDocument doc = new XmlDocument();
        // Get the Xml
        doc.LoadXml(xmlTest);
        // Get your DataSet Node
        XmlNode node = doc.SelectSingleNode("Object/DataSet");
        DataSet ds = new DataSet();
        // Read your node
        ds.ReadXml(new StringReader(node.OuterXml));
        // Read your daat
        string value = ds.Tables["TableOne"].Rows[0]["ItemID"];

as xml is not well format it is not possible to use the DOM parser. So you can the string manipulation

 string fileContent =  System.IO.File.ReadAllText(@"sample.xml");
        int firstIndex =  fileContent.IndexOf("<DataSet>", 0);
        int lastIndex = fileContent.IndexOf("</DataSet>", firstIndex);
        string data = fileContent.Substring(firstIndex + "<DataSet>".Length, lastIndex - firstIndex - "<DataSet>".Length);

Data contents the your dataset part
