Unmarshalled object to JSON?

[sytolk]

It is written that this library can turn XML into JSON. I'm trying to write Node.js proxy that turn SOAP service into Rest (media JSON). And I have successful unmarshal XML response from SOAP service. The problem is that I cannot send JSON model from const unmarshall. unmarshall Object is:

nodeName: 'ns2:GetFuelStationsResponse',
  tagName: 'ns2:GetFuelStationsResponse',
  namespaceURI: 'http://schemas.mobility-media.com/wsdl/fuelprice/v1',
  prefix: 'ns2',
  localName: 'GetFuelStationsResponse',
  parentNode:  ...

How about to have method unmarshall.toJson() to extract values from this object?
This is my code:

const context = new Jsonix.Context([envelope, getFuelStationResponse]);
const unmarshaller = context.createUnmarshaller();

// Unmarshal the XML file
const unmarshall = unmarshaller.unmarshalString(xml);
//to get JSON string is not possible from  unmarshall
console.log(unmarshall.value.body.any[0].childNodes[0].childNodes[1].childNodes);

Something is wrong with your mappings, you seem to get DOM object, probably your any property is mapped as DOM element and does not have a corresponding type.

Normally, if everything's mapped you should be getting pure JSON. Please PR your test project under https://github.com/highsource/jsonix-support/f/fuelprice, I'll see about it.

Here's the XML you try to unmarshall:

The problem is that your schemas/mappings do not contain mappings for the GetFuelStationsResponse element. So Jsonix does not know how to unmarshal this element and therefore leaves DOM.

Please augment your schemas/mappings with top level element for GetFuelStationsResponse and corresponding types. You should have a global element like
<xs:element name="getFuelStationsResponse" type="GetFuelStationsResponseType"/> or similar somewhere.

[sytolk]

Yes you are right this is mapping problem. I have fix it and push changes here:
https://github.com/sytolk/jsonix-support/tree/master/f/fuelprice.
Maybe it's need to have exception/warning in log for the mapping problem before Jsonix to leaves DOM?
I don`t know if this is OK but after body element from schema -> envelope.xsd its have any[0].getFuelStationsResponse.xsd This is the code that display parsed JSON now:

console.log(JSON.stringify(unmarshalled.value.body.any[0].value));

t.e. it's have two value for the two XSL schemas separated with any[0] or it's have some problem with body element mapping too. but this is not a big problem..
Can I skip TYPE_NAME JSON property? I think it is useless I only want to return JSON string in response (like Rest service do this) and use the same Mapping objects in Rest client app.

"fuelStation":{"TYPE_NAME":"getFuelStationsResponse.FuelStation","id":50014, ...

It`s fixed now thanks @highsource

Could you please share an example on your fix? Thanks.

[sytolk]

@vasyland I have change library to strong-soap + ws for SOAP (XML) to JSON converter

const soap = require('strong-soap').soap;
const ws = require('ws.js');
const XMLHandler = soap.XMLHandler;
const xmlHandler = new XMLHandler();
 const ctx = {
            request: request
            , url: url
            , action: "urn:" + endpoint
            , contentType: "text/xml"
        };

        const handlers = [new ws.Http()];

        ws.send(handlers, ctx, function (ctx) {
            const root = xmlHandler.xmlToJson(null, ctx.response, null); 
        });
