output xml  with columns as attributes to web browser from Oracle using asp.net with C#

This question is specific to Oracle database. I already know how to achieve this using SQL Server but with sql server I use the Select FOR XML AUTO command but for some reason that won't work with oracle. Then I tried another method shown below with oracle. I am close to getting what I need.

This example is using the HR database that comes with Oracle 10g express edition.
This example uses the EMPLOYEES table in the HR database.

I'm using ASP.net with C# to get data from 3 columns in my oracle table. I want the data from those 3 columns to be output to the browser as xml. I can get the xml to the browser with the following script but it's not the correct format I need.

I called the following script   Employees.aspx

<%@ Page Language="C#" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Configuration" %>
<%@ Import Namespace="System.Data.OracleClient" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
string connStr = "Data Source=127.0.0.1;User ID=HR;Password=HR;Unicode=True";
using (OracleConnection conn = new OracleConnection(connStr))
{
OracleCommand command = new OracleCommand("select FIRST_NAME, LAST_NAME, EMAIL from
EMPLOYEES", conn);
conn.Open();
DataSet ds = new DataSet();
ds.DataSetName = "EMPLOYEES";
ds.Load(command.ExecuteReader(), LoadOption.OverwriteChanges, "EMPLOYEE");
Response.ContentType = "text/xml";
ds.WriteXml(Response.OutputStream);
}
}
</script>

The above scripts outputs xml to the browser that looks like this:

<EMPLOYEES>
  <EMPLOYEE>
    <FIRST_NAME>Steven</FIRST_NAME>
    <LAST_NAME>King</LAST_NAME>
    <EMAIL>SKING</EMAIL>
  </EMPLOYEE>
  <EMPLOYEE>
    <FIRST_NAME>Neena</FIRST_NAME>
    <LAST_NAME>Kochhar</LAST_NAME>
    <EMAIL>NKOCHHAR</EMAIL>
  </EMPLOYEE>
  <EMPLOYEE>
    <FIRST_NAME>Lex</FIRST_NAME>
    <LAST_NAME>De Haan</LAST_NAME>
    <EMAIL>LDEHAAN</EMAIL>
  </EMPLOYEE>
  <EMPLOYEE>
    <FIRST_NAME>Alexander</FIRST_NAME>
    <LAST_NAME>Hunold</LAST_NAME>
    <EMAIL>AHUNOLD</EMAIL>
  </EMPLOYEE>
</EMPLOYEES>


But I need it to output the xml with the table columns as attributes, so I need it to look like this.
Can anyone help with getting by xml from oracle to output to the browser to look like this:


<?xml version="1.0" encoding="utf-8" ?>
<EMPLOYEES>
<EMPLOYEE FIRST_NAME="Steven" LAST_NAME="King" EMAIL="SKING" />
<EMPLOYEE FIRST_NAME="Neena" LAST_NAME="Kochhar" EMAIL="NKOCHHAR" />
<EMPLOYEE FIRST_NAME="Lex" LAST_NAME="De Haan" EMAIL="LDEHAAN" />
<EMPLOYEE FIRST_NAME="Alexander" LAST_NAME="Hunold" EMAIL="AHUNOLD" />
</EMPLOYEES>
