JSON Root value

[walkermic]

I have an IDOC listener that will receive json files of different formats. The root of the json file will be different for the different types. I need to evaluate the root value(PEXR2002 in this example) and then route it based on the value to other child pipelines. I cannot figure out how to get the value out. Anyone know?
