%% Description  : Callback module for exporting 
%%		   complete or simple forms to XML.

-module(xmerl_xml).

-export(['#xml-inheritance#'/0]).

-export(['#root#'/4,
	 '#element#'/5,
	 '#text#'/1]).

-import(xmerl_lib, [markup/3, empty_tag/2, export_text/1]).

-include("xmerl.hrl").
-include("xmerl_internal.hrl").


'#xml-inheritance#'() -> [].


%% The '#text#' function is called for every text segment.

'#text#'(Text) ->
%?dbg("Text=~p~n",[Text]),
    export_text(Text).


%% The '#root#' tag is called when the entire structure has been
%% exported. It does not appear in the structure itself.

'#root#'(Data, [#xmlAttribute{name=prolog,value=V}], [], _E) ->
    [V,Data];
'#root#'(Data, _Attrs, [], _E) ->
    ["<?xml version=\"1.0\"?>", Data].


%% The '#element#' function is the default handler for XML elements.

'#element#'(Tag, [], Attrs, _Parents, _E) ->
%?dbg("Empty Tag=~p~n",[Tag]),
    empty_tag(Tag, Attrs);
'#element#'(Tag, Data, Attrs, _Parents, _E) ->
%?dbg("Tag=~p~n",[Tag]),
    markup(Tag, Attrs, Data).
