From a mail by Hans-Joachim Ehlers (http://lists.opennebula.org/pipermail/users-opennebula.org/2013-February/022188.html):

For automation it would be nice to have a defined output format support by an additional option like "-F | --format" 

Where format could be : stanza , xml , {}  or what ever is useful and reliable. Might ease command output handling .

Example:
 --format S # Stanza

ServiceComponent:
    Service=<service_name>
    Name=<component_name>
    Module=<module_name>
    ComponentDataSize=<size>

 --format X # XML
<ServiceComponent>
...
</ServiceComponent>

Format selection should be selectable using a single parameter. "--format" seems a good candidate.
