不应为xmlns=''>。- XML文档(2，2)中存在错误

Question

我正在尝试反序列化来自this simple web service的响应

我正在使用以下代码：

WebRequest request = WebRequest.Create("http://inb374.jelastic.tsukaeru.net:8080/VodafoneDB/webresources/vodafone/04111111");    
WebResponse ws = request.GetResponse();
XmlSerializer s = new XmlSerializer(typeof(string));
string reponse = (string)s.Deserialize(ws.GetResponseStream());

Answer 1

将XmlSerializer声明为

XmlSerializer s = new XmlSerializer(typeof(string),new XmlRootAttribute("response"));

就足够了。

Answer 2

您希望对XML进行反序列化，并将其视为片段。

有一个非常简单的变通方法可用here。我已经针对您的场景进行了修改：

var webRequest = WebRequest.Create("http://inb374.jelastic.tsukaeru.net:8080/VodafoneDB/webresources/vodafone/04111111");

using (var webResponse = webRequest.GetResponse())
using (var responseStream = webResponse.GetResponseStream())
{
    var rootAttribute = new XmlRootAttribute();
    rootAttribute.ElementName = "response";
    rootAttribute.IsNullable = true;

    var xmlSerializer = new XmlSerializer(typeof (string), rootAttribute);
    var response = (string) xmlSerializer.Deserialize(responseStream);
}

我在将“声明了2个命名空间的xml字符串”反序列化为object时也遇到了同样的错误。

<?xml version="1.0" encoding="utf-8"?>
<vcs-device:errorNotification xmlns:vcs-pos="http://abc" xmlns:vcs-device="http://def">
    <errorText>Can't get PAN</errorText>
</vcs-device:errorNotification>

[XmlRoot(ElementName = "errorNotification", Namespace = "http://def")]
public class ErrorNotification
{
    [XmlAttribute(AttributeName = "vcs-pos", Namespace = "http://www.w3.org/2000/xmlns/")]
    public string VcsPosNamespace { get; set; }

    [XmlAttribute(AttributeName = "vcs-device", Namespace = "http://www.w3.org/2000/xmlns/")]
    public string VcsDeviceNamespace { get; set; }

    [XmlElement(ElementName = "errorText", Namespace = "")]
    public string ErrorText { get; set; }
}

通过使用XmlAttribute将字段添加到ErrorNotification类中，可以实现反序列化。

public static T Deserialize<T>(string xml)
{
    var serializer = new XmlSerializer(typeof(T));
    using (TextReader reader = new StringReader(xml))
    {
        return (T)serializer.Deserialize(reader);
    }
}

var obj = Deserialize<ErrorNotification>(xml);
