%XMLDEMO1 Demonstrate how to create an XML tree and save it
%
%   Description
%   This script demonstrates the use of the xmltree class to
%   create an XML tree from scratch and save it in a file.

%   Copyright (C) 2003  Guillaume Flandin

%   Please note that this script is only a demonstration of how
%   to use xmltree, set, add, view and save methods.
%   Indeed in this example, the use of the struct2xml function
%   would have been much more efficient:
%     entry = struct(...); % cf line 51
%     addressBook = struct('entry',entry);
%     tree = struct2xml(addressBook);
