Getting the JSON output in an object format for a single record instead of an array using XQuery - xquery

Question

I am getting JSON output from an API in an array format(for multiple records) and in object format for a single record. Instead consumer wants to maintain one format - as an array for single record also. Please let me know if there is a way to display the JSON output in array format irrespective of single/multiple records using XQuery
I have tried the below XQuery:
<Response>
<totalSize>{totalSize/number()}</totalSize>
<done>{done/text()}</done>
<nextRecordsUrl>{nextRecordsUrl/text()}</nextRecordsUrl>
{
let $input:=/root/records
for $i in $input
return
<records>
<Product1>{$i/Product_Lookup_BI__c/text()}</Product1>
<EventLastModifiedDate>{$i/LastModifiedDate/text()}</EventLastModifiedDate>
<Venue>{$i/Venue_vod__r/(fn:concat(fn:concat(fn:concat(fn:concat(fn:concat(fn:concat(BI_Country_Code__c/text(),'-'),State_Province_vod__c/text()),'-'),City_vod__c/text()),'-'),Address_vod__c/text()))}</Venue>
{
let $a:=$i/EM_Event_Team_Member_vod__r/records
for $y in $a
return
<User_records>
<AttendeeLastModifiedDate>{$y/LastModifiedDate/text()}</AttendeeLastModifiedDate>
<EmployeeName>{$y/Team_Member_vod__r/Name/text()}</EmployeeName>
<EmployeeID>{$y/Team_Member_vod__r/BIDS_ID_BI__c/text()}</EmployeeID>
</User_records>
}
</records>
}
</Response>
Actual Output from the above XQuery:
{
"Response": {
"totalSize": 1,
"done": true,
"nextRecordsUrl": "",
"records": {
"Product1": "12345",
"EventLastModifiedDate": "2021-11-10T01:30:55.000+0000",
"Venue": "UK",
"User_records": {
"AttendeeLastModifiedDate": "2021-11-08T02:55:03.000+0000",
"EmployeeName": "Ish",
"EmployeeID": "00002113152"
}
}
}
}
Expected Output:
The Output should be in an array format for "records" & "user_records"
{
"Response":{
"totalSize":1,
"done":true,
"nextRecordsUrl":"",
"records":[
{
"Product1":"12345",
"EventLastModifiedDate":"2021-11-10T01:30:55.000+0000",
"Venue":"UK",
"User_records":[
{
"AttendeeLastModifiedDate":"2021-11-08T02:55:03.000+0000",
"EmployeeName":"Ish",
"EmployeeID":"00002113152"
}
]
}
]
}
}

Answer 1

Try:
<User_records xmlns:json="http://www.json.org" json:array="true">
<AttendeeLastModifiedDate>{$y/LastModifiedDate/text()}</AttendeeLastModifiedDate>
<EmployeeName>{$y/Team_Member_vod__r/Name/text()}</EmployeeName>
<EmployeeID>{$y/Team_Member_vod__r/BIDS_ID_BI__c/text()}</EmployeeID>
</User_records>
I would do the same for <records> as well. This example works in eXist-db. The JSON namespace may be different in your environment.
Here is what I ran in eXide:
xquery version "3.1";
declare option exist:serialize "method=json indent=yes media-type=application/json";
<Response>
<totalSize>5</totalSize>
<done>yes</done>
<nextRecordsUrl>abc</nextRecordsUrl>
<User_records xmlns:json="http://www.json.org" json:array="true">
<AttendeeLastModifiedDate>123</AttendeeLastModifiedDate>
<EmployeeName>456</EmployeeName>
<EmployeeID>789</EmployeeID>
</User_records>
</Response>
