WebApi force action to return xml

I have this action:

public IHttpActionResult SearchFor(int aboItemType, DTO.FilterColumns filter)
{
    //Do stuff...
    return Ok<DataSet>(ds);
}

My client does:

client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/xml"));

var response = client.PostAsJsonAsync(myurl).Result;
if (response.IsSuccessStatusCode)
{
    var results = HttpUtility.HtmlDecode(response.Content.ReadAsStringAsync().Result);
}

The above scenario works perfectly. However, if I comment the Accept line, the action returns the dataset in json format.

I would like to force this one particular action to always send the result in xml. Is this possible? Maybe with an attribute?

Also you can do this (in the case you have to pass some http header values):

public IHttpActionResult Get()
{
    var result = Request.CreateResponse(HttpStatusCode.OK, 
                                        model,
                                        Configuration.Formatters.XmlFormatter);

    result.Headers.Add("Access-Control-Allow-Origin", "*");

    return ResponseMessage(result);
}

I used Сonfiguration.Formatters.XmlFormatter

public IHttpActionResult Get()
{
 ...
  return Content(HttpStatusCode.OK, Model, Configuration.Formatters.XmlFormatter);
}
