How to see ARRAY with NODE JS soap - node.js

Question

Hi need to make a WebService with nodejs, this is my first experience to make a SOAP with WSDL.
I use the library "node-wsdl" and i need to stamp a list of array in soap but now i receive a wrong response
I have this response from SOAP:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tns="http://localhost:3001/gateway">
<soap:Body>
<tns:listInvoicesResponse>
<tns:0>
<invoice_id>00000</invoice_id>
<ipa_code>00000</ipa_code>
<timing>Thu Jun 04 2015 16:35:46 GMT+0100 (GMT+01:00)</timing>
</tns:0>
<tns:1>
<invoice_id>00001</invoice_id>
<ipa_code>00001</ipa_code>
<timing>Thu Jun 04 2015 16:41:29 GMT+0100 (GMT+01:00)</timing>
</tns:1>
</tns:listInvoicesResponse>
</soap:Body>
</soap:Envelope>
But i need to have a response like this:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tns="http://localhost:3001/gateway">
<soap:Body>
<tns:listInvoicesResponse>
<lists>
<tns:0>
<invoice_id>00000</invoice_id>
<ipa_code>00000</ipa_code>
<timing>Thu Jun 04 2015 16:35:46 GMT+0100 (GMT+01:00)</timing>
</tns:0>
<tns:1>
<invoice_id>000</invoice_id>
<ipa_code>00001</ipa_code>
<timing>Thu Jun 04 2015 16:41:29 GMT+0100 (GMT+01:00)</timing>
</tns:1>
</lists>
</tns:listInvoicesResponse>
</soap:Body>
</soap:Envelope>
I use this code for retrive info from a DB and print the result on XML like list
var myService = {
ws: {
gateway: {
listInvoices: function(args, callback) {
var ipa_code = args.ipaCode
GetAllInvoice(ipa_code).then(result =>{
console.log(result)
result.map( el =>{
callback(result)
})
})
},
// This is how to define an asynchronous function.
getInvoice: function(args, callback) {
// do some work
}
}
}
};
And my wsdl is this
