your problem appears here:

nesne.getarticle_byte().tostring()

i'm not familiar nesne class, can tell method, getarticle_byte() returns byte array, calling tostring() on homecoming useless info you're seeing, , if needs stored, somehow need store entire array. using loop , storing array string representations of each byte not efficient thing , lead super-large unreadable xml, perhaps store off of xml , pass reference byte array file in xml. or store in database blob. note not much of, , i'm no expert.
