Element is not known in this context, could not determine its type, or trying to use marshaller.

[gitowiec]

Hi
I have an issue while using the marshaller. I am new to JSONIX and I would like to convert JavaScript object to XML document. I generated mapping based on Schemat_JPK_FA(1)_v1-0.xsd file (in the project).
Could You @highsource please take a look and tell me why I get "Element [JPK] is not known in this context" error?

Here is my project
https://github.com/gitowiec/jsonix-tryout

And here is sample of XML I want to get from JSON:

<?xml version="1.0" encoding="UTF-8"?>
<JPK xmlns="http://jpk.mf.gov.pl/wzor/2016/03/09/03095/" xmlns:ns2="http://crd.gov.pl/xml/schematy/dziedzinowe/mf/2016/01/25/eD/DefinicjeTypy/">

I've sent you a PR with the fix:

gitowiec/jsonix-tryout#1

There were three problems with your code:

• Main problem was that you use require('./mappings/JPK') as mapping, should be require('./mappings/JPK').JPK. Generated modules export mappings as a property of the mapping's name.
• For {JPK: value} to work, your target namespace has to be associated with the empty namespace.
• In JSON, you should use property names as generated in mappins. Like, nip instead of NIP.

With a few fixes I could generate the following XML:

<?xml version="1.0" encoding="UTF-8"?>
<JPK xmlns="http://jpk.mf.gov.pl/wzor/2016/03/09/03095/" xmlns:ns2="http://crd.gov.pl/xml/schematy/dziedzinowe/mf/2016/01/25/eD/DefinicjeTypy/">

Thank You Very Much for Your Support,
Is it possible to pretty print XML string and make new lines after every > closing of opening tag?
I can't find API document where I could lookup parameters of marshaller.marshalString()

[highsource]

You're welcome.

No, there are now built-in support for pretty-printing. Jsonix uses standard XMLSerializer which, as far as I know, does not support pretty-printing. Quick SO search did not produce any good results.

If you figure this out, please let me know.

[gitowiec]

I used this package to pretty print XML https://www.npmjs.com/package/xml-formatter
And if I may ask, is there option to make marshaller.marshalString() allow using key names (localName's) beginning with UpperCase and not stripping underscore? Just make it leave property names unchanged?
I would like this behaviour because using cxsd package I can generate TypeScript types for JSON data structure and that types have property names same as original element names (Naglowek instead of naglowek, Podmiot1 instead of podmiot1, P_2A instead of p2A, and so on)

[highsource]

And if I may ask, is there option to make marshaller.marshalString() allow using key names (localName's) beginning with UpperCase and not stripping underscore?

No, not at the moment. File a feature request if you want this.

[gitowiec]

Ok I think it's a jsonix-schema-compiler feature so I just reported feature-request there highsource/jsonix-schema-compiler#82

[highsource]

Correct. Well done, thanks!
