how can I deserialize this xml from netforum?

Question

I've been googling this since Friday, and tearing my hair out all morning.

I've got some xml coming back from netforum that coming back from a call to WEBCommitteeGetCommitteeListAsync.

The response that comes back is not an xmldocument, and has a series of childnodes inside WEBCommitteeGetCommitteeListResult. Each node looks like the below item (but I changed the data to protect the innocent):

<Result xmlns="http://www.avectra.com/2005/">
  <cmt_key>a guid I clipped out</cmt_key>
  <cmt_code>ICTF</cmt_code>
  <cmt_name>a committee name</cmt_name>
  <cmt_ctp_code>Task Force</cmt_ctp_code>
  <cmt_begin_date />
  <cmt_end_date />
  <cmt_description>the committee description</cmt_description>
</Result>

I created a model class using https://xmlgrid.net/xml2xsd.html as below:

public class NFCommittee
{
    [XmlRoot(ElementName = "Result")]
    public class Result
    {
        [XmlElement(ElementName = "cmt_key")]
        public string Cmt_key { get; set; }
        [XmlElement(ElementName = "cmt_code")]
        public string Cmt_code { get; set; }
        [XmlElement(ElementName = "cmt_name")]
        public string Cmt_name { get; set; }
        [XmlElement(ElementName = "cmt_ctp_code")]
        public string Cmt_ctp_code { get; set; }
        [XmlElement(ElementName = "cmt_begin_date")]
        public string Cmt_begin_date { get; set; }
        [XmlElement(ElementName = "cmt_end_date")]
        public string Cmt_end_date { get; set; }
        [XmlElement(ElementName = "cmt_description")]
        public string Cmt_description { get; set; }
        [XmlAttribute(AttributeName = "xmlns")]
        public string Xmlns { get; set; }
    }
}

The code I'm using to deserialize each childnode is:

XmlSerializer serializer = new XmlSerializer(typeof(NFCommittee));
System.Xml.XmlNodeReader oReader = new System.Xml.XmlNodeReader(childNode);
NFCommittee convertedItem = (NFCommittee)serializer.Deserialize(oReader);

The error I get is {"http://www.avectra.com/2005/'> was not expected."}

Obviously I'd prefer to convert the entire list of childnodes in one go, but I'm not even able to convert the individual childnodes and I'm not sure why.

Edit: the original class looked like this but it had the exact same result, so I tried taking out the namespace.

[XmlRoot(ElementName = "Result", Namespace = "http://www.avectra.com/2005/")]
public class Result
{
    [XmlElement(ElementName = "cmt_key", Namespace = "http://www.avectra.com/2005/")]
    public string Cmt_key { get; set; }
    [XmlElement(ElementName = "cmt_code", Namespace = "http://www.avectra.com/2005/")]
    public string Cmt_code { get; set; }
    [XmlElement(ElementName = "cmt_name", Namespace = "http://www.avectra.com/2005/")]
    public string Cmt_name { get; set; }
    [XmlElement(ElementName = "cmt_ctp_code", Namespace = "http://www.avectra.com/2005/")]
    public string Cmt_ctp_code { get; set; }
    [XmlElement(ElementName = "cmt_begin_date", Namespace = "http://www.avectra.com/2005/")]
    public string Cmt_begin_date { get; set; }
    [XmlElement(ElementName = "cmt_end_date", Namespace = "http://www.avectra.com/2005/")]
    public string Cmt_end_date { get; set; }
    [XmlElement(ElementName = "cmt_description", Namespace = "http://www.avectra.com/2005/")]
    public string Cmt_description { get; set; }
    [XmlAttribute(AttributeName = "xmlns")]
    public string Xmlns { get; set; }
}

The following works :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Serialization;



namespace ConsoleApplication1
{
    class Program
    {
        const string filename = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XmlReader reader = XmlReader.Create(filename);
            XmlSerializer serializer = new XmlSerializer(typeof(NFCommittee.Result));

            NFCommittee.Result result = (NFCommittee.Result)serializer.Deserialize(reader);
        }
    }
    public class NFCommittee
    {
        [XmlRoot(ElementName = "Result", Namespace = "")]
        public class Result
        {
            [XmlElement(ElementName = "cmt_key")]
            public string Cmt_key { get; set; }
            [XmlElement(ElementName = "cmt_code")]
            public string Cmt_code { get; set; }
            [XmlElement(ElementName = "cmt_name")]
            public string Cmt_name { get; set; }
            [XmlElement(ElementName = "cmt_ctp_code")]
            public string Cmt_ctp_code { get; set; }
            [XmlElement(ElementName = "cmt_begin_date")]
            public string Cmt_begin_date { get; set; }
            [XmlElement(ElementName = "cmt_end_date")]
            public string Cmt_end_date { get; set; }
            [XmlElement(ElementName = "cmt_description")]
            public string Cmt_description { get; set; }
            [XmlAttribute(AttributeName = "xmlns")]
            public string Xmlns { get; set; }
        }
    }

}
