function varargout = xml2mat(xmlfile, matfile)
%XML2MAT Convert an XML-file into a MAT-file
%  XML2MAT(XMLFILE, MATFILE) converts an XML file or an XML string
%  (as saved by MAT2XML) into a MAT-file MATFILE.
%  S = XML2MAT(XMLFILE) returns the content of XMLFILE in variable S.
%  S is a struct containing fields matching the variables retrieved.

% Bugs to handle:
%  o xml_parser replaces tabs and successive spaces into one even
%    in CData tags (=> pbs for char variables)
%  o still a bug with entities ?
%  o integer variables not handled
%  o proper handle of home made classes
%  o deal with precision loss with double variables (format)
%  o special handling of cellstr and struct array ?
%  o does it work with all Matlab releases ?
%  o if xmlfile is "empty" and nargout = 1 then error
%  o Use of 'eval' may reinitialize variables used in this function
