Selecting sql data with multiple rows and exporting as xml file - mirth

Question

I have this JavaScript in my transformer
var dbConn;
try {
dbConn = DatabaseConnectionFactory.createDatabaseConnection($gc('DataWarehouseXMLDataConfig').sqlDriver,
$gc('DataWarehouseXMLDataConfig').sqlConnString,
$gc('DataWarehouseXMLDataConfig').sqlUsername,
$gc('DataWarehouseXMLDataConfig').sqlPassword);
var data = dbConn.executeCachedQuery('EXEC [dbo].[GetDataWarehouseData]');
var xml = "";
var xml2 = "";
var row = "";
while(data.next()) {
row = '<referral>' + '\n' +
'<careid>' + data.getString('careid') + '</careid>' + '\n' +
'<patientid>' + data.getString('patientid') + '</patientid>' + '\n' +
'<dateofreceipt>' + data.getString('dateofreceipt') + '</dateofreceipt>' + '\n' +
'<datefirstseen>' + data.getString('datefirstseen') + '</datefirstseen>' + '\n' +
'<nhsnumber>' + data.getString('nhsnumber') + '</nhsnumber>' + '\n' +
'<hospitalnumber>' + data.getString('hospitalnumber') + '</hospitalnumber>' + '\n' +
'<surname>' + data.getString('surname') + '</surname>' + '\n' +
'<forename>' + data.getString('forename') + '</forename>' + '\n' +
'<dateofbirth>' + data.getString('dateofbirth') + '</dateofbirth>' + '\n' +
'</referral>';
xml = xml + row;
xml2 = '<?xml version="1.0" encoding="utf-8"?>' + '\n' + '<results>' + xml + '</results>';
}
channelMap.put('xml2', xml2);
} finally {
if (dbConn) {
dbConn.close();
}
}
I'm using this outbound message template
<referral>
<careid></careid>
<patientid></patientid>
<dateofreceipt></dateofreceipt>
<datefirstseen></datefirstseen>
<nhsnumber></nhsnumber>
<hospitalnumber></hospitalnumber>
<surname></surname>
<forename></forename>
<dateofbirth></dateofbirth>
</referral>
I have a File Writer destination and the File Name has a .xml extension.
My template in the File Writer is ${XmlUtil.prettyPrint(${message.encodedData})}.
The SQL data is being retrieved ok.
I don't think I'm a million miles away but I'm doing something fundamentally wrong.
What do I need to do to send the required xml file please?

Answer 1

I fixed this by adding a mapping step to the source transformer and using JavaScript, like
tmp['referral']['dateofbirth'] = msg['dateofbirth'].toString();
