Parameterizing elements of an SDF model

I'm new to Gazebo and I've been trying to create a SDF model for a general wall I'll be using in a Vicon space. I'm using aau gazebo vicon to modify the pose of my wall model, but, because I have eight walls, I need to figure out how to parameterize the ros topic they listen to.

Specifically, the code I'm trying to modify is:

<plugin name="ros_transform" filename="/home/cohrint/catkin_ws/devel/lib/">

How can I change <transformTopic>/vicon/Wall1/Wall1</transformTopic> to <transformTopic>/vicon/Wall(n)/Wall(n)</transformTopic> where (n) is the nth wall loaded into gazebo?

I have recently been using embedded ruby (erb) to parameterize sdf models. Here's an example of a parameterized vehicle model using erb. For that example I use erb model.rsdf > model.sdf to generate the model.sdf file.

Hmm, that won't quite work for me. I'd rather not have a different model for each wall, I was hoping to simply have one model that reads from a ROS Topic based on, say, the object name or the order in which the object was created.

@nckswt Although I agree with you on not duplicating SDF files, its challenge is explained here by @scpeters, which I don't quite understand but I just took it as a compelling reason.
