ArrayList for XML help

[tulielf]

Hi,

I've got no errors for compiling but I can't figure out why there isn't any stored output when I save them into a XML file.

thanks!

Current output

<?xml version="1.0" encoding="utf-8" ?>
<AirlineArray xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xsi:nil="true" />


Wanted output

<?xml version="1.0" encoding="utf-8"?>
<AirlineArray xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<airlineList>
<RFQSave>
<quotationId>1234</quotationId>
<supplier>1301</supplier>
<prodName>Singapore Airline</prodName>
<classType>Economy Class</classType>
<adultQuantity>4</adultQuantity>
<childQuantity>4</childQuantity>
</RFQSave>
</airlineList>
</AirlineArray>

Array to store RFQSave
