Invalid roslaunch XML syntax: not well-formed dji package

Question

When i try to launch the package by typing

roslaunch dji_sdk sdk.launch

where the launch file content :

launch>
    <node pkg="dji_sdk" type="dji_sdk_node" name="dji_sdk" output="screen">
    <!-- node parameters -->
    <param name="serial_name" type="string" value="/dev/ttyTHS0"/>
    <param name="baud_rate" type="int" value="921600"/>
    <param name="app_id" type="int" value="1079440"/>
    <param name="app_version" type="int" value="1"/>
    <param name="align_time" type="bool" value="false"/>
    <param name="enc_key" type="string" value="39d353a8e9ad01b6c659111904bae57ebb138785aa5159699383f28da3f56563"/>
    <param name="use_broadcast" type="bool" value="false"/>
    </node>
</launch>

it gives me this error :

I started with sourcing the workspace and catkin_make after that i rosed the launch file to edit four things: value of app_id, enc_key, serial_name to ttyTHS0, and baud_rate. and then i tried to launch the dji_sdk sdk,launch however it replayed me with the error that i have previously shared. — Ibtesam ali, Oct 12 '19 at 13:29
please edit your post. upload error and content within the sdk.launch. high chance you made a syntax error inside. e.g missing " > or \ . shows content inside "/home/dji/.ros/log/4bf6ba22-eb1e-11e9-acf7-74da38ebc18f/roslaunch-manifold2-4798.log" as well . please re-think how others can help you — Dr Yuan Shenghai, Oct 12 '19 at 14:48
@DrYuanShenghai actually it was downloaded along with dji sdk package so i don't know. — Ibtesam ali, Oct 15 '19 at 03:44
@DrYuanShenghai yes it did, but i got another error, which i post about it earlier today — Ibtesam ali, Oct 15 '19 at 06:47
..bro high chance it is another small mistake. in real world, no one is going to follow you all the way and help you troubleshoot. you need to read and error and understand them — Dr Yuan Shenghai, Oct 15 '19 at 07:44

the error here was because of missing < in the first line.
