As you can see above, the error occurs:
Skipping XML Document "/opt/ros/indigo/share/camera1394stereo/camera1394stereo_nodelet.xml" which had no Root Element. This likely means the XML is malformed or missing.
I cd to the directory and found no such file, so I downloaded the file from github and put it there.

however, the problem was still unsolved, no error occurred any more but the warning still occurs:
......

......
Then I run:
rosrun image_view image_view image:=/camera/rgb/image_color
No image showed, the information showed above updated:

[ WARN] [1427507860.193522626]: Camera calibration file /home/krist/.ros/camera_info/rgb_PS1080_PrimeSense.yaml not found.
How to solve it, any suggestions?

The camera1394stereo message likely has nothing to do with your openni2 problem.

I don't know why these two packages are related, maybe it's because xtion has mutiple cameras.
