Invalid roslaunch XML syntax: no root <launch> tag
I am quite new to ROS. I would like to what I should do? I have a capstonerobot.urdf file and a capstonerobot.launch file

**My launch file
<launch>
<!-- Load the capstonerobot URDF model into the parameter server -->
<param name="robot_description" textfile="$(find capstonerobot)/capstonerobot.urdf" />
<!-- Start Gazebo with an empty world -->
<include file="$(find gazebo_ros)/launch/empty_world.launch"/>
<!-- Spawn a capstonerobot in Gazebo, taking the description from the
parameter server -->

</launch>
Please use the
preformatted textbutton to format your error message and your launch file. As it is now it's quite difficult to read.while it's works for me, maybe you should check
empty_world.launchor you should just get a new launch file and retype it.
