Error deserializing XML to code generated class

Question

I’m trying to get data from a web service that returns XML. The web service also provide XSD file that I converted to a class using XsdToCode fromCodeplex.

Unfortunately I’m getting an error. I don’t know why and how to solve this so any help would be appreciated. The error is as followed:

There is an error in XML document (1, 2).

Innerexeption: {"http://www.opengis.net/xls'> was not expected."}

Source: System.Xml

Here’s the sample URL that I’m calling to get the XML

http://geodata.nationaalgeoregister.nl/geocoder/Geocoder?zoekterm=grote+markt+groningen

This returns the Following XML





233818.478 582036.58



Grote Markt

Groningen
Groningen
Groningen

Below is the code to retrieve the XML and deserialize it to an object class

        var request = WebRequest.Create(url);
        var response = (HttpWebResponse)request.GetResponse();
        var serializer = new XmlSerializer(typeof(GeocodeResponse));

        var i = (GeocodeResponse)serializer.Deserialize(new StreamReader(response.GetResponseStream()));

        return i;

Here is a part is the class that i need the XML deserialized into

public class GeocodeResponse
{

    // ELEMENTS
    [XmlElement("GeocodeResponseList")]
    public GeocodeResponseList GeocodeResponseList { get; set; }

    // CONSTRUCTOR
    public GeocodeResponse()
    {}
}

Just for completion I also included the XSD file on where I generated the code from using XsdToCode.

Thanx in advance for any help.

You have to inform the serializer about the namespace in the xml, so pass it into the constructor of the serializer.

Change the line that instantiates the serializer:

var serializer = new XmlSerializer(typeof(GeocodeResponse));

to:

var serializer = new XmlSerializer(typeof(GeocodeResponse), "http://www.opengis.net/xls");
