XML Deserializing "Element was not expected" error

Question

I know this has been asked before, but I checked the other threads and none were of help to me. I am trying to deserialize an xml to an object and am getting the error:

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

My XML looks like:

<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>

The code I am using to deserialize with looks like:

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);

And the object I am trying to deserialize too looks like: (shortened version)

I have tried adding:

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

To the top of the class I am trying to deserialize too, with no luck. I have also tried changing the XmlSerializer object to:

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);

This would work, but every type in the deserialized object would return null, even though they are all populated in the xml document.

Any help would be great, thanks!

Answer 1

I put your xml into a file 'test.xml' and then ran xsd test.xml. This resulted in 'test.xsd' and 'test_app1.xsd'. I added the schema elements from test_app1.xsd to test.xsd and then ran xsd.test.xsd /classes.

This resulted in:

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

Now running the following code in LINQPad, works fine.

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();
}
