XML反序列化“未预期元素”错误

标签: c# xml xml-deserialization

我知道之前已经问过这个问题,但我检查了其他线程,没有人对我有所帮助。我试图将xml反序列化为对象并收到错误:

"<doPublish xmlns='http://usdoj.gov/leisp/lexs/publishdiscover/3.1'> 
   was not expected."

我的XML看起来像:

<lexspd:doPublish xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://usdoj.gov/leisp/lexs/publishdiscover/3.1 ../xsd/lexs/publish-discover/3.1/publish-discover.xsd"
    xmlns:lexspd="http://usdoj.gov/leisp/lexs/publishdiscover/3.1"
    xmlns:lexs="http://usdoj.gov/leisp/lexs/3.1">
    <lexs:PublishMessageContainer>
        <lexs:PublishMessage>
            <lexs:PDMessageMetadata>
            </lexs:PDMessageMetadata>
        </lexs:PublishMessage>
    </lexs:PublishMessageContainer>
</lexspd:doPublish>

我用来反序列化的代码如下:

XmlSerializer xs = new XmlSerializer(typeof(PublishMessageType));
Encoding encode = new UTF8Encoding();

PDWebService lexpdServiceProxy = new PDWebService();
lexpdServiceProxy.Url = "http://59.60.72.12/";

String pdMessageXml = File.ReadAllText(fileName);

DoPublishType doPublishType = new DoPublishType();
MemoryStream publishMsgMemStream = new MemoryStream(encode.GetBytes(pdMessageXml));
doPublishType.PublishMessageContainer = new PublishMessageType[1];
doPublishType.PublishMessageContainer[0] =
   (PublishMessageType)xs.Deserialize(publishMsgMemStream);

我试图反序列化的对象看起来像:(缩短版本)

我尝试过添加:

[System.Xml.Serialization.XmlRoot("doPublish", Namespace = "http://usdoj.gov/leisp/lexs/publishdiscover/3.1", IsNullable = true)]

在课堂上我也试图反序列化,没有运气。 我也尝试将XmlSerializer对象更改为:

XmlRootAttribute xRoot = new XmlRootAttribute();
xRoot.ElementName = "doPublish";
xRoot.Namespace = "http://usdoj.gov/leisp/lexs/publishdiscover/3.1";
xRoot.IsNullable = true;
XmlSerializer xs = new XmlSerializer(typeof(PublishMessageType), xRoot);

这样可行,但反序列化对象中的每个类型都将返回null,即使它们都填充在xml文档中。

任何帮助都会很棒,谢谢!

我将您的xml放入文件'test.xml',然后运行xsd test.xml。 这导致'test.xsd'和'test_app1.xsd'。 我将test_app1.xsd中的架构元素添加到test.xsd,然后运行xsd.test.xsd / classes。

这导致:

        get {

        }

        }

        }
    }

        }
        set {
            this.itemsField = value;
        }
    }
}

现在在LINQPad中运行以下代码,工作正常。

using(var stream = File.Open(@"..path here..\test.xml", FileMode.Open))
{
    XmlRootAttribute xRoot = new XmlRootAttribute();
    xRoot.ElementName = "doPublish";
    xRoot.Namespace = "http://usdoj.gov/leisp/lexs/publishdiscover/3.1";
    xRoot.IsNullable = true;

    var serializer = new XmlSerializer(typeof(doPublish), xRoot);

    var root = (doPublish)serializer.Deserialize(stream);

    root.Dump();
}

答案 1 :(得分:0)

在两种情况下,名称空间可能都必须相同。被拒绝的XML片段最后缺少“/ ws”。
