get_text() always returns the base64 in axis2/c too. In addition there
is also a get_data_handler() function which returns the data handler.
But the problem here that I see, is that we use axiom_node_to_string()
which optimizes the output xml, if MTOM optimized flag is set on a
text node. (Correct me if I'm wrong)

So the solution here would be either to do it as Kaushalye explained
in #2 or to use a different serialization function which ignores the
MTOM optimized flag, I guess.
