Hello @prarthana.sigedar ,

This error message means that your XML file, the launch file, may have a syntax error.

Could you copy and paste the content of this file here?

Thank you

Your launch file should have the <launch> tag.
Also, remove the extra spaces in the <node> tag.
Should be something like:

<!-- My Package launch file -->
<launch>
  <node pkg="turtlebot3_move" type="turtlebot3_sub_pub.py" name="turtlebot3_node" output="screen">
  </node>
</launch>
