Is it possible to customize Json element's Datatype as per Json schema?

Question

Converting XML to JSON through StAXON parser, there are datatype mismatch between Json Schema (expected) and actual Response JSON

For ex: As per Swagger Schema, we are expecting a “String” value for a field but XML to JSON parser gives us “Integer” which is not matching with Swagger/Schema document.

In Swagger/Json Schema accountId type mentioned as String.

"accountId" : {
            "type" : "string",
            "description" : "The Id of the account",
            "readOnly" : true
          }

The XML element value of accountId is: < accountId>123</ accountId> After converting XML to JSON the accountId is: **123** but as per schema our expectation is accountId: **“123”**

Universal parsing logic of XML to JSON:

1. If the element has only Numbers but starts with Zero: <accountId>0123</accountId> then Json output is: String { accountId : “0123” }
2. If the element has only Numbers but not starts with Zero: <accountId>123</accountId> then Json output is: Integer { accountId : 123 }
3. If the element has contains character: <accountName>Abc</ accountName> then Json output is: String { accountName : “Abc”)

It will convert Json as per the data, not with any schema, obviously I didn't feed any schema while parsing Staxon parser.

Is there any way I can change the JSON which should match with the expect Json schema. As per the above scenario I am expecting a String value, it should look at the schema and make the datatype of a field. Note: Don't want to convert all to String as well.

Thanks in advance!!!
