PIDF XML Deserialisierung nach RFC 3863

Question

Ich versuche, Aktivität in Objekttyp Aktivitäten nach dem RFC (konvertierte XSD zu C# -Klasse mit der XSD in der RFC) zu deserialisieren, aber es scheint, dass ich Probleme mit der Aktivität XML-Element, da es einen inneren Namensraum im Attribut enthält.

XML:

<?xml version="1.0" encoding="UTF-8" standalone="no" ?> 
<presence xmlns="urn:ietf:params:xml:ns:pidf" entity="sip:anon@domain.invalid" xmlns:e="urn:ietf:params:xml:ns:pidf:status:rpid" xmlns:dm="urn:ietf:params:xml:ns:pidf:data-model" xmlns:ce="urn:cisco:params:xml:ns:pidf:rpid" xmlns:sc="urn:ietf:params:xml:ns:pidf:servcaps"> 
    <dm:person> 
    <status> 
    <basic>open</basic> 
    </status> 
    <e:activities> 
    </e:activities> 
    </dm:person> 
</presence> 

ich dies in eine Präsenzobjekt am Deserialisieren, den ersten (presence.Any [0]) nehmen, und dies in einer Person, Objekt deserialisieren, ist alles so weit in Ordnung. Aber dann möchte ich das Aktivitätselement von Person zu nehmen, und deserialisieren dies:

person.Any.SingleOrDefault(x => x.LocalName == "activities") 

Aber jetzt ist die XML dieses Objekts wie folgt aussieht:

<e:activities xmlns:e="urn:ietf:params:xml:ns:pidf:status:rpid"> 
    </e:activities> 

Und wenn ich versuche, dies in eine Tätigkeit deserialisieren Objekt als von XSD in RFC3863, ich bin mit der Endung der folgenden Fehlermeldung:

Message "<activities xmlns='urn:ietf:params:xml:ns:pidf:status:rpid'> was not expected." 

wie kann ich deserialisieren XmlElements, die einen inneren Namespace wie folgt enthält ??

UPDATE 23-11-17 (Elemente, die leer ist):

XML:

<?xml version="1.0" encoding="ISO-8859-1"?> 
<presence xmlns="urn:ietf:params:xml:ns:pidf" xmlns:pp="urn:ietf:params:xml:ns:pidf:person" xmlns:es="urn:ietf:params:xml:ns:pidf:rpid:status:rpid-status" xmlns:ep="urn:ietf:params:xml:ns:pidf:rpid:rpid-person" entity="sip:Alice@10.24.18.124"> 
    <pp:person> 
     <status> 
      <ep:activities> 
       <ep:away/> 
      </ep:activities> 
     </status> 
    </pp:person> 
    <note>Unavailable</note> 
    <tuple id="6001"> 
     <contact priority="1">sip:6001@10.24.18.124</contact> 
     <status> 
      <basic>closed</basic> 
     </status> 
    </tuple> 
</presence> 

Problem:

<ep:away xmlns:ep="urn:ietf:params:xml:ns:pidf:rpid:rpid-person" />

Sie muss die Namensräume entsprechend deklarieren sicher, vor allem die Standard-Namespaces. Siehe Arbeits Code unten:

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

namespace ConsoleApplication1 
{ 
    class Program 
    { 
     const string INPUT_FILENAME = @"c:\temp\test.xml"; 
     const string OUTPUT_FILENAME = @"c:\temp\test1.xml"; 
     static void Main(string[] args) 
     { 

      Presence outPresence = new Presence() 
      { 
       person = new Person() 
       { 
        status = new Status() 
        { 
         basic = "test" 
        }, 
        activities = new Activities() 
        { 
        } 
       } 
      }; 
      XmlSerializerNamespaces xmlNameSpace = new XmlSerializerNamespaces(); 
      xmlNameSpace.Add("dm", "urn:ietf:params:xml:ns:pidf:data-model"); 
      xmlNameSpace.Add("e", "urn:ietf:params:xml:ns:pidf:status:rpid"); 
      xmlNameSpace.Add("", ""); 

      XmlSerializer serializer = new XmlSerializer(typeof(Presence), "urn:ietf:params:xml:ns:pidf"); 

      XmlWriterSettings settings = new XmlWriterSettings(); 
      settings.Indent = true; 

      XmlWriter writer = XmlWriter.Create(OUTPUT_FILENAME, settings); 
      serializer.Serialize(writer, outPresence, xmlNameSpace); 

      StreamReader reader = new StreamReader(INPUT_FILENAME); 

      Presence presense = (Presence)serializer.Deserialize(reader); 
     } 

    } 
    [XmlRoot(ElementName = "presence")] 
    public class Presence 
    { 
     [XmlElement(ElementName = "person", Namespace = "urn:ietf:params:xml:ns:pidf:data-model")] 
     public Person person { get; set; } 
    } 
    [XmlRoot(ElementName = "person", Namespace = "urn:ietf:params:xml:ns:pidf:data-model")] 
    public class Person 
    { 
     [XmlElement(ElementName = "status", Namespace = "urn:ietf:params:xml:ns:pidf")] 
     public Status status { get; set; } 

     [XmlElement(ElementName = "activities", Namespace = "urn:ietf:params:xml:ns:pidf:status:rpid")] 
     public Activities activities { get; set; } 
    } 
    [XmlRoot(ElementName = "status", Namespace = "urn:ietf:params:xml:ns:pidf")] 
    public class Status 
    { 
     [XmlElement("basic")] 
     public string basic { get; set; } 
    } 
    [XmlRoot(ElementName = "activities", Namespace = "urn:ietf:params:xml:ns:pidf:status:rpid")] 
    public class Activities 
    { 
    } 
}
