Get all style element inside a Civil 3D Project File and rename it

As per the Camber package, where nodes like Surface Style fetch the file and then use Style.SetName can rename the file. What I need is to fetch all the style items at once and then filter them by specific rules, and then rename them. But I can not get all the style elements in Dynamo. Can anyone guide me on how I collect all the style elements inside the document?
