JSON to XML to JSON conversion not the same

[federico-piazza]

Hi guys,

I've have the following JSON:

{
        "RESULTS": [
            {
                "@elem": 0,
                "ACCOUNT_OBJ": "",
                "END_T": 0,
                "POID": ""
            }
        ]
}

When I transform it to XML the result is:

<?xml version="1.0" encoding="UTF-8"?><flist>
  <RESULTS elem="0">
    <ACCOUNT_OBJ/>
    <END_T>0</END_T>
    <POID/>
  </RESULTS>
</flist>

And when I transform it back to JSON using:

JsonXMLConfig config = new JsonXMLConfigBuilder()
                .autoPrimitive(true)
                .build()

The resulting JSON is:

{
        "RESULTS": [
            {
                "@elem": "0",
                "ACCOUNT_OBJ": null,
                "END_T": 0,
                "POID": null
            }
        ]
}

Not sure if I'm doing something wrong or misunderstood the autoPrimitive flag but I get the string "0" for @elem instead of the primitive 0. Is this a bug?

On the other hand, I know the convention is that <POID/> is converted to "POID":null. Is it possible to transform it back to empty string?

Also, another problem is that whitespaces string like " " are converted to null.
