Complete export of SAP XI elements to an external, readable format i.e. XML

Within the scope of a project regarding Dependencies of Applications within the company the data, saved in the Integration Directory as well as in the Integration Repository, have to be exported in an external, readable format which can be processed in another application. My question is concerned with the extraction possibilities I have concerning the different components:

Integration Repository: Here we need the data about Message Interfaces, Message Types as well as Data Types. As this information are formally described using WSDL: Does a possibility exist to export all WSDL Documents automatically?

Integration Directory: Here we are interested in the elements: Receiver Determination, Interface Determination, Sender Agreement etc. Does any possibility exist to export these data to i.e. a XML File? Is ABAP necessary?

Your help will be greatly appreciated.

Kind Regards,
