Adriano - I think you are asking the wrong question because it doesn't make sense.
When you read/parse a PDF, there can only be ONE Document Catalog object in the active PDF document. The reason is because that object is determined by the value of the /Root key in the CURRENT Trailer. Once you have that object, it will start your "tree walk" to all other objects in the current/active PDF.
