Ejabberd module do not compile after update

Question

I, i have updated ejabberd from 16.01 to 16.03, i have a problem with my module, before update this line of code

Type = Packet#xmlel.attrs,
    io:format("types:~p~n" , [Type]),
    %Get raw data of message
    Message         = xml:element_to_binary(Packet).

works fine, now after update produce this:

types:[{<<"type">>,<<"chat">>}, {<<"to">>,<<"154@node0.frind.it">>},
       {<<"from">>,<<"121@node0.frind.it">>}]

Latest ejabberd move to library fast_xml . Use fxml module instead of xml .
