Convert JSON to SOAP XML with predefined namespaces

Question

I am given task to convert SOAP request to ReST JSON and then JSON back to SOAP XML. I have done the part of converting SOAP to JSON with Serialize and XMlElement() classes. Now the trickiest part comes where I need to convert JSON to SOAP. There are our own namespaces which are written and I want to put those namespaces back as well when converting JSON to SOAP XML. For example,

<asr:APIRequest

xmlns:guid-"http://Some-test-namespace.xsd" xmlns:xsi="https://www.w3.org/2001/XMLSchema" xmins:asw="http://Some-test-namespace.xsd" xmIns:ar="http://Some-test-namespace.xsd" xmlns:asr="http://Some-test-namespace.xsd">

<asr:APIRequestDetails>

<ar:Individual>

<ar:IndividualKey>3791239123-123123123-1231231</ar:IndividualKey>

</ar:Individual> 

</asr:APIRequestDetails> 
</asr:APIRequest>

I converted it to JSON

{
  "APIRequest": {
    "APIRequestDetails": {
      "Individual": {
        "IndividualKey": "3791239123-123123123-1231231"
      }
    }
  }
}

Now I want to convert it back to SOAP XML with the namespaces that are attached such as 'asr', 'ar'. I am using C# .Net Core and used XDocument, XMLSerializer for converting XML to JSON.

can anyone please help me converting JSON back to SOAP XML with the NAMESPACES as well?

You OBVIOUSLY can't as JSON doesn't contain this informations. — Selvin, Sep 21 '22 at 10:43
ok ... An example: we convert list {2, 3, 4} to list {4, 3, 2} ... now we can't get {2, 3, 4} from {4, 3, 2} again — Selvin, Sep 21 '22 at 10:45
don't say it is impossible then. I asked to get the answers, not to listen "it's impossible" — Makki Anjum, Sep 21 '22 at 10:47
You didn't wrote that you have models ... so I thought that you need a generic solution for [any JSON conversion to XML](https://dotnetfiddle.net/Khfg5k) - which is possible but without namespaces (and array element names)... **but JSON in your question seems doesn't matter at all and all you asking is how to serialize model to xml with namespaces** — Selvin, Sep 21 '22 at 15:00
... which simply make this question a duplicate of https://stackoverflow.com/questions/2339782/xml-serialization-and-namespace-prefixes — Selvin, Sep 21 '22 at 15:06

Namespace do not get added unless used. Try following

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

namespace ConsoleApplication40
{
    class Program
    {
        const string INPUT_FILENAME = @"c:\temp\test.xml";
        const string OUTPUT_FILENAME = @"c:\temp\test1.xml";
        static void Main(string[] args)
        {
            XmlReader reader = XmlReader.Create(INPUT_FILENAME);
            XmlSerializer serializer = new XmlSerializer(typeof(APIRequest));
            APIRequest request = (APIRequest)serializer.Deserialize(reader);

            XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces();
            namespaces.Add("guid", "http://Some-test-namespace.xsd");
            namespaces.Add("xsi", "https://www.w3.org/2001/XMLSchema");
            namespaces.Add("asw", "http://Some-test-namespace.xsd");
            namespaces.Add("ar", "http://Some-test-namespace.xsd");
            namespaces.Add("asr", "http://Some-test-namespace.xsd");

            XmlWriterSettings settings = new XmlWriterSettings();
            settings.Indent = true;
            XmlWriter writer = XmlWriter.Create(OUTPUT_FILENAME,settings);
            serializer.Serialize(writer, request, namespaces);
        }

    }
    [XmlRoot(Namespace = "http://Some-test-namespace.xsd")]
    public class APIRequest
    {
        [XmlElement(Namespace = "http://Some-test-namespace.xsd")]
        public APIRequestDetails APIRequestDetails { get; set; }
    }
    public class APIRequestDetails
    {
        [XmlElement(Namespace = "http://Some-test-namespace.xsd")]
        public Individual Individual { get; set; }
    }
    public class Individual
    {
        [XmlElement(Namespace = "http://Some-test-namespace.xsd")]
        public string IndividualKey { get; set; }
    }
}

This doesn't answer the question which is how to convert given JSON back SOAP XML... Also OP didn't mention that he has model classes — Selvin, Sep 21 '22 at 11:13
@Selvin can you please stay away from this question. I don't need your answer. — Makki Anjum, Sep 21 '22 at 11:33
@Selvin : Next time read the posting completely. The OP said he already was using xml serialization in the process. the OP just said he was having issues with the namespaces. — jdweng, Sep 21 '22 at 11:43
@Selvin : Posting didn't say to stop using XDocument. My posting did answer the question. Sevin you are answering a completely different question. — jdweng, Sep 21 '22 at 12:22
