I Have a SOAP web services which takes XML as input and send XML as response. Now I have a JSON object which is the same as XML request. How can I convert JSON Object to XML so that I can send the XML request to my SOAP web service. I have the WSDL file. In other terms, I wanted to provide a extra layer of REST on top of SOAP
A JSON object can never be "the same as" an XML document, because the data models are different. It may hold the same information, but the problem is that there is no definitive mapping from JSON to XML that is guaranteed to produce the XML representation that you are after.
There are a number of libraries available that do JSON to XML conversion: give them a try, but you will probably have to "tweak" the XML to get it into the required form. That can always be done using XSLT, of course.
If you use XSLT 3.0 then you can do the JSON to XML conversion and subsequent processing ("tweaking") in a single step.

I want to know what is the best way to convert XML to JSON in MarkLogic.
I use json:transform-to-json, but it does not give the proper response. Also it slows the service response a lot.
My XML has attributes or you can say search:search response data.
I need to create a Logic Apps workflow with three steps:
When HTTP Request is received (JSON)
Convert Json from request to XML
Save XML file to FTP
What I have done so far:
Add action "When HTTP Request is received"
Add Liquid to Convert JSON to XML
(but i don't see option JSON to XML...Only Tranform JSON to JSON, JSON to
TEXT, XML to JSON, XML to TEXT)
Add action "FTP - Create file"
I also created Integration Account and try to add map for mapping JSON to XML, but I can't find any examples/templates to do this...
Is it possible at all ? Maybe there is another way to convert between these two formats ?
When you just want to convert a JSON payload to an XML file, without doing any transformation to the data, you can use the built-in xml() function of the Workflow Definition Language.
Detailed info in the docs: Workflow Definition Language reference #xml
I've made a small test Logic App to demo your usecase. It looks like this:
As you can see I use the xml function on the triggerbody #xml(triggerBody()) as an input for my FTP file content.
Remark: This will only work if your JSON message has a single rootnode. Otherwise the xml conversion will fail. You'll get this error:
The provided value cannot be converted to XML: 'JSON root object has multiple properties. The root object must have a single property in order to create a valid XML document. Consider specifying a DeserializeRootElementName.
You can work around that by concatenating a rootnode to your JSON payload. The function then would look like: #xml(json(concat('{\"rootnode\":',triggerBody(),'}')))
Good luck testing this out. Let me know if you need more help with this.
In Talend, I have a job that received XML messages (of different structures) and call a web service with those messages. The tRestClient component automatically transforms the Xml into JSON when it calls my web service.
In case of an error, I want to save my message locally in JSON. Is there a component in Talend to automatically transform the XML into JSON (like the tRestClient do)?
I'm defining the structure of JSON documents. I'd like to know if how to validate the JSON documents against existing XSD, RelaxNG schemas or another standard schema language schema. I know of Jsonix, but I don't see that it uses the regular expressions from XSD or RelaxNG for validation against JSON schema (and I don't think that JSON schema is standardized).
Clarification: We already have existing XML and XSD. We can always go back to XML for validation, but it would be cool if we could validate the JSON directly, and would give us more confidence when we want to use the JSON and not XML.
Update: Here is the specification in question: http://www.web3d.org/specifications/x3d-3.4.xsd note that it doesn't have text nodes in the XML documents.
Preliminary answer (still a work in progress, but you can contribute):
If you want to convert XML schema to JSON schema, try downloading: XSD2OWL stylesheet which converts XML Schema to OWL. I converted my schema to owl like this:
$ xmlsh
$ xslt -f xsd2owl.xsl -cf file.xsd > file.owl
$ exit
Then download owl2jsonschema.js ** NO LICENSE ** and modify it until it until the demo works. The output will be in demo/OUTPUT/schema folder/*.json as separate JSON files.
XSD and RelaxNG are defined against XML, not JSON.
For JSON, see JSON Schema, but realize that it has nowhere near the adoption of XSD, and the latest draft of the specification expired August 3, 2013, casting doubts on the future of the effort.
Update
How do I validate JSON against XML Schema (XSD) or RelaxNG?
You don't.
The question is not "Can I?" but "How?" Say I have total control over
the JSON document.
When the answer to "Can I?" is "No" the question of how does not apply.
Clarification: We already have existing XML and XSD. We can always go
back to XML for validation, but it would be cool if we could validate
the JSON directly, and would give us more confidence when we want to
use the JSON and not XML.
You can validate the JSON directly against a JSON Schema, but not against an XSD. There are no tools that can do that; the standards are substantially different. The need to define standard vocabularies and grammars that is served by XSD and RelaxNG against XML was intended to be met by JSON Schema against JSON.
You're looking for "confidence when we want to use the JSON and not XML" in the wrong place. See reasons for choosing XML vs JSON instead.
As you're probably already aware of the information I'm about to post, this is just for reference.
Jsonix Schema Compiler supports generation of JSON Schema based on the XML Schema.
So with this you can convert you XML Schema into JSON Schema and validate your JSON against this JSON Schema using AJV.
This is still an experimental feature but that's the direction.
Hi I am new to Java and not sure how to proceed (kindly ignore any typos or my language). Can somebody help me out (just the Idea/how to proceed, dont need any sample code). I am trying to create a Restful Json webservice (using Spring MVC).
The webservice that I am trying to create is kind of a wrapper for an existing XML based restful webservice.
The Idea is to have one common platform, since all other existing services are exposed as as JSON services.
My job is to fetch the XML transform it into a Json, but the tricky part is The Json schema is a superset of the XML schema (I mean it contains more elements that get filled with some default values).
Please let me know if you need more info.
Thanks in advance.
One way to do it would be to use Jaxb to transform the the incoming XML to Java Objects. Build your Jaxb objects in a way that it contains all the elements, the one with default values and the elements in the incoming XML.
Ones the XMl is converted into Jaxb you can use org.springframework.http.converter.json.MappingJacksonHttpMessageConverter message converter to convert your Jaxb object to Json string.
