How to return xml from Web Api

Question

I'm trying to return the following xml from a web api

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE cXML SYSTEM "http://xml.cxml.org/schemas/cXML/1.2.014/cXML.dtd">
<cXML payloadID="payloadID" xml:lang="en" timestamp="2019-12-12T12:57:27-08:00">
  <Response>
    <Status code="200" text="OK" />
  </Response>
</cXML>

but the actual return is

<cXML payloadID="payloadID" xml:lang="en" timestamp="2019-12-12T12:57:27-08:00">
<Response>
<Status code="200" text="OK" />
</Response>
</cXML>

here's a code snippet

[HttpPost("api/[controller]/{format}"), FormatFilter]
    public IActionResult Post([FromBody] AribaPurchaseOrder.Order Order)
    {
        // Process Order .......

        //Ariba order response
        var response = "";
        response += @"<?xml version=""1.0"" encoding=""UTF-8""?>";
        response += @"<!DOCTYPE cXML SYSTEM ""http://xml.cxml.org/schemas/cXML/1.2.014/cXML.dtd"">";

        response += $@"<cXML payloadID=""{Order.PayloadID}"" xml:lang=""en"" timestamp=""{GetAribaFormatTimeStamp()}"">";
        response += @"<Response>";
        response += @"<Status code=""200"" text=""OK""/>";
        response += @"</Response>";
        response += @"</cXML>";

        return new ObjectResult(response) { StatusCode = 200 };
    }

Can anyone advise how to send the response in the correct format?

How are you reading the response. The missing line may be sent put the viewer may not be displaying the missing lines. — jdweng
