syntax error near unexpected token 'newline'

I have cloned the "robot_localization" package and made it catkin but when I am trying to run the nodes I am getting an error like

syntax error near unexpected token 'newline'

'newline'

my launch file are as following

ekf_template.launch

<launch>
  <node pkg="robot_localization" type="ekf_localization_node" name="ekf_se" clear_params="true">
    clear_params="true"&gt;
    <rosparam command="load" file="$(find robot_localization)/params/ekf_template.yaml" />
  </node>
</launch>

ukf_template.launch

<launch>
  <node pkg="robot_localization" type="ukf_localization_node" name="ukf_se" clear_params="true">
    clear_params="true"&gt;
    <rosparam command="load" file="$(find robot_localization)/params/ukf_template.yaml" />
  </node>

Can anyone please tell me how to resolve this issue ?

Thanks

Are you 'running nodes' or trying to compile the packages? Posting code and actual errors will help.

Why did you clone and compile this versus installing it via your package manager?

Hi,

Thank you very much for your kind reply. I catkin_make the package.Now I am trying to run the example node file. I have already made it executable.I am receiving the following error

/home/nvidia/myworkspace/src/robot_localization/test/test_ukf_localization_node_bag1.test: line 1: syntax error near unexpected token newline' /home/nvidia/myworkspace/src/robot_localization/test/test_ukf_localization_node_bag1.test: line 1: '

In order to use the robot localization package do i have to install the "sudo apt-get ros-kinetic-robot-localization" apart from cloning the github ?

Can you please tell me where I am making error ?

Thanks

How can I set up the localization package in order to work with it. I have attached my topic in the launch file. But when I am running the command like rosrun robot-loclization ukf_localization_node it's not working properly.

ekf_template.launch

<!--  Placeholder for output topic remapping
<remap from="odometry/filtered" to="/ins"/>
<remap from="accel/filtered" to="/imu"/>
-->

ukf_template.launch

<!--  Placeholder for output topic remapping
<remap from="odometry/filtered" to="/ins"/>
<remap from="accel/filtered" to="/imu"/>
-->

Please add all of this to your original question.

Use the edit button/link for that. Do not post code/console output more than a few lines in comments.

@Dina please don't completely change the question after it's been answered. If the answer solved your problem please mark it as correct. If you have a new question then please ask a new question

Your ukf_template.launch file is missing the closing launch tag. It should be

<launch>
  <node pkg="robot_localization" type="ukf_localization_node" name="ukf_se" clear_params="true">
    <rosparam command="load" file="$(find robot_localization)/params/ukf_template.yaml" />
  </node>
</launch> <!-- This was missing -->

If this isn't it, then please update your question with the full error. It should give a file name and line number.
