title: I need help on XSLT
body: <p>This is the payload to transform :</p>
  
  <pre><code>&lt;result&gt;
  &lt;invoice0&gt;201762133&lt;/invoice0&gt; 
  &lt;invoice1&gt;201730800&lt;/invoice1&gt;
  &lt;invoice2&gt;2016419446&lt;/invoice2&gt;
  &lt;totalAmmount0&gt;10208.32&lt;/totalAmmount0&gt; 
  &lt;totalAmmount1&gt;10196.62&lt;/totalAmmount1&gt;
  &lt;totalAmmount2&gt;10196.62&lt;/totalAmmount2&gt;
  &lt;status0&gt;Open&lt;/status0&gt; 
  &lt;status1&gt;Open&lt;/status1&gt;
  &lt;status2&gt;Closed&lt;/status2&gt;
  &lt;date0&gt;30/03/2017&lt;/date0&gt;
  &lt;date1&gt;28/02/2017&lt;/date1&gt;
  &lt;date2&gt;30/01/2017&lt;/date2&gt;
  &lt;invoiceAmmount&gt;3&lt;/invoiceAmmount&gt; 
  &lt;/result&gt;
  </code></pre>
  
  <p>So, I can't change this payload before the transformation, and I'm not managing to delivery this way:</p>
  
  <pre><code>&lt;result&gt;
  &lt;invoiceNumber&gt;201762133,201730800,2016419446&lt;/invoiceNumber&gt; 
  &lt;totalAmmount&gt;10208.32,10196.62,10196.62&lt;/totalAmmount&gt;
  &lt;statusInvoice&gt;Open,Open,Closed&lt;/statusInvoice&gt;
  &lt;dueDate&gt;30/03/2017,28/02/2017,30/01/2017&lt;/dueDate&gt;
  &lt;invoiceAmmount&gt;3&lt;/invoiceAmmount&gt; 
  &lt;/result&gt;
  </code></pre>
  
  <p>Question: Is it possible? How?</p>
