How do I create my own XML-Tag (instead of <no-name>)?

Hi Drupal-fans,

is it possible to change the XML-tag for fields?
Right now my XML-output is looking like this:

<nodes>
   <node>
      <no-name>Title 1</no-name>
   </node>
   <node>
      <no-name>Title 2</no-name>
   </node>
</nodes>

But I would like to have a <title>-Tag instead of the <no-name> thing. I didn't find any setting to achieve this :-/

Thank you!
