xml to dataset

[aneeshmm]

i use the following code to write sql data to xml file.

SqlDataAdapter ad = new SqlDataAdapter("SELECT	name AS [@label],	salary AS [@value] FROM	Employee FOR XML	PATH('set'),ROOT('chart')", cnn);
        cnn.Close();
        DataSet ds = new DataSet("chart");
        ad.Fill(ds,"set");        
        XmlDataDocument doc = new XmlDataDocument(ds);
        doc.Save(Server.MapPath(Request.ApplicationPath)+"\\t.xml");

i get the file as

<chart>
<set>
<xml>
<chart>
<set label=""abcd value="abcd" />
</chart>
</xml>
</set>
</chart>

i want to remove the first three tags; ie, <chart>,<set> and <xml>
