I hope, you are looking for retrieving the processing rules from this content. I could not find any service that lists the Processing Rules. The output string from this service displays a standard ff structure (see below). This data can be made as readable IS doc by creating a ff schema to parse the structure, but it just depends on what is your exact requirement.
