Hi

I like to use roslaunch to start a rosbag recording with regular expression arguments. How to I substitute the double quote "" to avoid xml problems The following launch code is NOT working.

<launch>  
  <node pkg="rosbag" type="rosbag" name="rosbag" args="record -e "(.*)image_raw"  "(.*)camera_info" " />
</launch>

Any ideas

Greetings Markus

The correct entity escape in XML for quot is "

You could also use single quotes, ', inside the outer set of "".
