How to convert Database Response to Json response using groovy script

I have two responses one is Web Service Response:

{
"summary": {
"apiVersion": "V1",
"apiName": "GetDataContextReferences"
},
"errors": null,
"action": "COMPLETE",
"warnings": null,
"dataContextReference": [
{
"id": 2,
"name": "LIVE"
},
{
"id": 3,
"name": "STAGING"
},
{
"id": 1,
"name": "DRAFT"
},
{
"id": 4,
"name": "ARCHIVE"
}
]
}

2. JDBC Response 

<Results>
<ResultSet fetchSize="0">
<Row rowNumber="1">
<DATA_CONTEXT_REFERENCE_LOOKUP.ID>2</DATA_CONTEXT_REFERENCE_LOOKUP.ID>
<DATA_CONTEXT_REFERENCE_LOOKUP.NAME>LIVE</DATA_CONTEXT_REFERENCE_LOOKUP.NAME>
</Row>
<Row rowNumber="2">
<DATA_CONTEXT_REFERENCE_LOOKUP.ID>3</DATA_CONTEXT_REFERENCE_LOOKUP.ID>
<DATA_CONTEXT_REFERENCE_LOOKUP.NAME>STAGING</DATA_CONTEXT_REFERENCE_LOOKUP.NAME>
</Row>
<Row rowNumber="3">
<DATA_CONTEXT_REFERENCE_LOOKUP.ID>1</DATA_CONTEXT_REFERENCE_LOOKUP.ID>
<DATA_CONTEXT_REFERENCE_LOOKUP.NAME>DRAFT</DATA_CONTEXT_REFERENCE_LOOKUP.NAME>
</Row>
<Row rowNumber="4">
<DATA_CONTEXT_REFERENCE_LOOKUP.ID>4</DATA_CONTEXT_REFERENCE_LOOKUP.ID>
<DATA_CONTEXT_REFERENCE_LOOKUP.NAME>ARCHIVE</DATA_CONTEXT_REFERENCE_LOOKUP.NAME>
</Row>
</ResultSet>
</Results><Results>

<DATA_CONTEXT_REFERENCE_LOOKUP.NAME>ARCHIVE</DATA_CONTEXT_REFERENCE_LOOKUP.NAME>

</Results>

How can I write a groovy script to match theses two outputs?
