java – XML to JSON conversion: why my 1st xml tag is getting skipped?

while converting XML to JSON my 1st XML tag into JSON is getting skipped

Here is the JAVA code snippet:

       String="";
       data = FileUtils.readFileToString(new File("src/main/resources/student.xml"), "UTF-8");
       XmlMapper xmlMapper = new XmlMapper();
       JsonNode jsonNode = xmlMapper.readTree(data.getBytes());
       ObjectMapper objectMapper = new ObjectMapper();
       objectMapper.writerWithDefaultPrettyPrinter().writeValue(newFile("src/main/resources/student.json"),jsonNode);

here is the input:

<?xml version="1.0" encoding="utf-8"?>
<AccumulateResponse>
  <TestCase>
    <Transactionid>str1234</Transactionid>
    <TransactionType>str1234</TransactionType>
    <Status>str1234</Status>
  </TestCase>
  <TestCase>
    <Transactionid>str5678</Transactionid>
    <TransactionType>str5678</TransactionType>
    <Status>str5678</Status>
  </TestCase>
</AccumulateResponse>

here is the output:

{
  "TestCase": [
   {
    "Transactionid": "str1234",
    "TransactionType": "str1234",
    "Status": "str1234"
   },
   {
    "Transactionid": "str5678",
    "TransactionType": "str5678",
    "Status": "str5678"
   }
  ]
}

here is the required Output:

{
"AccumulateResponse": {
  "TestCase": [
   {
    "Transactionid": "str1234",
    "TransactionType": "str1234",
    "Status": "str1234"
   },
   {
    "Transactionid": "str5678",
    "TransactionType": "str5678",
    "Status": "str5678"
   }
  ]
 }
}

AccumulateResponse tag is getting skipped.
