I have to make a call to a webservice but building the xml manually. I’ve chosen System.Xml to do this but it’s causing me a lot of pain.

Every SOAP I know consts of 3 parts:

The XmlDeclaration
The Header of the envelope or SOAP-ENV:Envelope
The
Body of the envelope or
SOAP-ENV:Body

The thing is my XmlDocument only can contain one root element. (Don’t know why)
If I do

MyXMLDoc.CreateNode(XmlNodeType.DocumentFragment, "SOAP-ENV", "Envelope", "http://tempuri.org");

It does not let me append attributes. It says those are read only.

RESUMING:

How do I have to do to write this but without the root and with an XmlDeclaration? and how do I call a webservice (with this xml)?

-<root>
  <SOAP-ENV:Envelope xmlns:SOAP-ENV=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xs=""http://www.w3.org/2001/XMLSchema"" />

For your specific question: in a SOAP envelope the Body element needs to be a child of the Envelope. You can’t have the envelope be an empty element and the body following it. The code below shows how to load a modified version of this document in a XmlDocument object.

    public class StackOverflow_6157636_751090
    {
        public static void Test()
        {
            string xml = @"  <SOAP-ENV:Envelope xmlns:SOAP-ENV=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xs=""http://www.w3.org/2001/XMLSchema""> 
 <SOAP-ENV:Body>
 <ZbcInsertRequest xmlns:ns1=""urn:sap-com:document:sap:soap:functions:mc-style"">
  <Destino>qas</Destino> 
 <IClrQst>
  <Request>foo</Request> 
  <Proyecto>foofoo</Proyecto> 
  <Modulocq /> 
  <Titureq>foofoofoo</Titureq> 
  <Tiporeq /> 
  <Prioridad>0</Prioridad> 
  <Clasific /> 
  <Asignadoa>foofoofoofoo</Asignadoa> 
  <Destino>qas</Destino> 
  <Solicita>foo</Solicita> 
  <Autoriza>c.foo</Autoriza> 
  <ModTransp /> 
  <ReqSox>F</ReqSox> 
  <Notfylst /> 
  <Tipodeploy>Normal</Tipodeploy> 
  <Paqdeploy>CDVQA00000000</Paqdeploy> 
  </IClrQst>
 <TRequest>
 <item>
  <Trkorr>DESK9A0ZJT</Trkorr> 
  <Secuencia>0</Secuencia> 
  <Solicita>c.foo</Solicita> 
  <Type /> 
  <Id /> 
  <Numero /> 
  <Message /> 
  </item>
  </TRequest>
  </ZbcInsertRequest>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>";
            XmlDocument doc = new XmlDocument();
            doc.LoadXml(xml);
            MemoryStream ms = new MemoryStream();
            Encoding encoding = new UTF8Encoding(false);
            XmlWriter w = XmlWriter.Create(ms, new XmlWriterSettings { Indent = true, OmitXmlDeclaration = false, Encoding = encoding, IndentChars = "  " });
            doc.Save(w);
            w.Flush();
            Console.WriteLine(encoding.GetString(ms.ToArray()));
        }
    }

Now, another option you can consider (if possible) is not to send the SOAP request “manually”, but use some tool (such as WCF or some other SOAP library) to create a proxy which you can use to send requests to the service. That way your client can simply “call a method” and the stack will take care of creating the SOAP envelope for you.
