Custom formatting of XML export

[oespanyol]

I export a list of elements based in example:
http://www.smartclient.com/smartgwtee/showcase/#custom_export

and I get the following output in XML:

<List>
  <Object>
    <Impact>data interrupted</Impact>
    <Subject>eclipse-season</Subject>
    <Type>Planned Maintenance</Type>
    <End Time>2014-09-29T22:00:00</End Time>
    <Satellites>MET-7</Satellites>
  </Object>
  <Object>
    <Impact>data interrupted</Impact>
    <Subject>eclipse-season</Subject>
    <Type>Planned Maintenance</Type>
    <End Time>2014-09-29T22:00:00</End Time>
    <Satellites>MET-7</Satellites>
  </Object>
</List>

However, I would like to get something more like:

<announcements>
  <announcement Impact="data interrupted" Subject="eclipse-season" Type="Planned Maintenance">
    <End Time>2014-09-29T22:00:00</End Time>
    <Satellites>MET-7</Satellites>
  </announcement>
  <announcement Impact="data interrupted" Subject="eclipse-season" Type="Planned Maintenance">
    <End Time>2014-09-29T22:00:00</End Time>
    <Satellites>MET-7</Satellites>
  </announcement>
</announcement>

That is, how do I:
1) change "List" to a value defined by me: "announcements"
2) change "Object" to a value defined by me: "announcement"
3) change elements into attributes, from instance Impact. This would be the equivalent as using annotations @XmlAttribute, @XmlElement

Is 3) possible at all? Or should I look into another way to implement the XML formatting different from the example above.

Thanks in advance,

You should just directly output the XML you want to the servlet OutputStream. See the next sample in that folder for sample code: "Custom Export (Custom Response)"
