CXTPPropExchange Section Name and Property name

/*

                i intend to read a write data structures using the CXTPPropExchange class,

                for that i planned to use a recursive function that read through the objects

                and retrieved it's children and read it's properties.

                i having some trouble reading the data in the CXTPPropExchange objects, despite my

                eforts it seems that i can't read a section name, nor a property name from the object.

                could you please confirm that there is a way to retrieve this data from the CXTPPropExchange object.

                bellow is a sample of what planned to do.

                                               it's name, using some option the the PX_ functions ?
