@hid123, edit your title so it's shorter and more meaningful and describe the problem in more detail. Which tutorial are you referring to etc.

@hid123, according to the error message there should be some error while parsing XML file. Can you provide us with some launch files etc? How do you run the whole thing?

This is really weird to me as I cannot see anything wrong with the launch file and my version of turtlesim is working just fine... What operating system do you use and how did you install the ROS distribution?
