convert StreamReader response to xml

Question

How can i parse the response to XML, in order to read the status number and so(i wrote an example at the bottom)?

 using (HttpWebResponse resp = req.GetResponse() as HttpWebResponse)
 {
                    if (resp.StatusCode == HttpStatusCode.OK)
                    {
                        var Obj_response = new CXML();
                        var ms = new StreamReader(resp.GetResponseStream(), UTF8Encoding.UTF8);      
                        t = ms.ReadToEnd();// <---- This line Caused the issue    



                        XmlSerializer serializer = new XmlSerializer(typeof(CXML));    
                        Obj_response = (CXML)serializer.Deserialize(ms);// <------ NOT WORKING

                        return true;
                    }
}

Response:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE cXML SYSTEM "http://xml.cXML.org/schemas/cXML/1.1.009/cXML.dtd">
<cXML payloadID="Web" xml:lang="en-US" timestamp="3/7/2016 5:21:43 AM"> 
<Response>
   <Status code="200" text="OK" />
   <JobID>WebOrder 69</JobID>
</Response>
</cXML>

PResponse obj:

[XmlRoot(ElementName = "Status")]
public class Status
{
    [XmlAttribute(AttributeName = "code")]
    public string Code { get; set; }
    [XmlAttribute(AttributeName = "text")]
    public string Text { get; set; }
}

[XmlRoot(ElementName = "Response")]
public class Response
{
    [XmlElement(ElementName = "Status")]
    public Status Status { get; set; }
    [XmlElement(ElementName = "JobID")]
    public string JobID { get; set; }
}

[XmlRoot(ElementName = "cXML")]
public class CXML
{
    [XmlElement(ElementName = "Response")]
    public Response Response { get; set; }
    [XmlAttribute(AttributeName = "payloadID")]
    public string PayloadID { get; set; }
    [XmlAttribute(AttributeName = "lang", Namespace = "http://www.w3.org/XML/1998/namespace")]
    public string Lang { get; set; }
    [XmlAttribute(AttributeName = "timestamp")]
    public string Timestamp { get; set; }
}

What i want to achieve:

if( xml.Status.code == 200){
// something to happen on successful request
}
else{
// write the response text to log
}

I also tried to do this

I have updated the question according to the suggestion that the XML classes should fully correspond the XML structure.

Well, your root element is "cXML" and not the "Response", so what do you expect? — Eugene Podskal, Mar 07 '16 at 12:51
i am expecting "What i want to achieve:" in the question. i now changed "Response" to "cXML" as i thought it will solve the problem, but it didnt — Eran Meir, Mar 07 '16 at 12:55
@EranMeir The Model type you use to parse the XML should fully correspond to the xml schema. So you should have at least three classes - one for cXML, one for Response and one for Status. And they shall obviously have appropriate names, types and attributes. You should read some XML deserialization tutorials. — Eugene Podskal, Mar 07 '16 at 12:59
@EugenePodskal - i used [this](http://xmltocsharp.azurewebsites.net/) site to create the right structure classes, but i am still getting an error `{"There is an error in XML document (0, 0)."}` — Eran Meir, Mar 07 '16 at 13:05
Perhaps doctype or some schema issues causes it - try http://stackoverflow.com/questions/4203540/generate-c-sharp-class-from-xml. Or just do it yourself - it has a tiny schema. — Eugene Podskal, Mar 07 '16 at 13:08
Please keep it to [one question](http://stackoverflow.com/questions/35841305/httpwebresponse-parse-to-xml), I have updated it with the XML structure and code. — CodeCaster, Mar 07 '16 at 13:12
@CodeCaster - so you do realize it is not related to the answers you posted as duplicate.. — Eran Meir, Mar 07 '16 at 13:27
@Eran you refused to update your existing question and posted a new one, that's not how it works. — CodeCaster, Mar 07 '16 at 13:45
@EranMeir Are you sure that your response is what you show to us? Perhaps it uses another encoding? What is the **exact error message** you get, because provided XML can be parsed into the given data models? — Eugene Podskal, Mar 07 '16 at 14:48
I updated the question with what caused the problem- " t = ms.ReadToEnd();" — Eran Meir, Mar 07 '16 at 14:50

You can try this approach:

Deserialize your xml:

XmlSerializer serializer = new XmlSerializer(typeof(cXML));

StreamReader reader = new StreamReader(path);
var obj = (cXML)serializer.Deserialize(reader);
reader.Close();

Object definition:

[Serializable]
[XmlRoot("cXML")]
public class cXML
{
    [XmlElement("Response")]
    public PResponse PResponse { get; set; } 
}


[Serializable]
public class Status
{
    [XmlAttribute("code")]
    public string Code { get; set; }

    [XmlAttribute("text")]
    public string Text { get; set; }
}

[Serializable]
public class PResponse
{
    [XmlElement("Status")]
    public Status Status { get; set; }

    [XmlElement("JobID")]
    public string PlanJobID { get; set; }
}

Did you read the question, or did you dump the XML into a class generator? — CodeCaster, Mar 07 '16 at 13:22
@CodeCaster, yes I read the question and this model will satisfy the needs of topic starter. He will be able to access "code" property by calling obj.PResponse.Status.Code from my code above — gos, Mar 07 '16 at 13:33
