How do you designate more than one animation (and name it) in blender before exporting with ogrexml?
I believe with actions, create a new action then (re)name it for each animation.
Using the old exporter, you then needed to add each action from a drop down list on the exporter screen (makes more sense when looking at the screen).
An example of blender2ogre exporter with multiple animations:
