Hello,

I have the following code in XML:

<?xml version="1.0" encoding="UTF-8"?>
<agency>
    <destinations>
        <destination id="bel">Belize</destination>
        <destination id="mad">Madeira</destination>
        <destination id="per">Peru</destination>
    </destinations>
    <traveler id="coelho">
        <passport>P-123456-08</passport>
        <name>Pedro Coelho</name>
        <born>1964-10-05</born>
        <trip>
            <start>2013-07-01</start>
            <end>2013-07-15</end>
            <itinerary destination="bel">
                Viagem em classe executiva para Belize via Frankfurt.
            </itinerary>
            <plane date="2013-07-01">
                Pedir refeição vegan.
                <airport>Barajas</airport>
                Alertar assistente antes da próxima ligação.
            </plane>
            <plane date="2013-07-01">
                Confirmado. Comparecer com 3 horas de antecedência.
                <airport>Frankfurt</airport>
            </plane>
                <hotel date="2013-07-01">Beach Resort</hotel>
                <hotel date="2013-07-08">Mountain Inn</hotel>
        </trip>
    </traveler>
    <traveler id="leite">
        <passport>P-456789-09</passport>
        <born>1970-12-25</born>
        <name>Fernanda Leite</name>
    </traveler>
</agency>

And the result in an xml file:

<?xml version="1.0" encoding="UTF-8"?>
<destinations>
  <destination id="bel">
    <trip start="2013-07-01" end="2013-07-15">
       <itinerary>
          Viagem em classe executiva para Belize via Frankfurt.
       </itinerary>
       <planes>2</planes>
     </trip>
  </destination>
  <destination id="mad"/>
  <destination id="per"/>
</destinations>
