function varargout=xmlwrite_xerces(varargin)
%XMLWRITE_XERCES Serialize an XML Document Object Model node using Xerces parser.
% xmlwrite_xerces(FILENAME,DOMNODE) serializes the DOMNODE to file FILENAME.
%
% The function xmlwrite_xerces is very similar the Matlab function xmlwrite
% but works directly with the XERCES java classes (written by Apache XML
% Project) instead of the XMLUtils class created by Mathworks. Xerces files
% are provided in standard MATLAB instalation and live in root\java\jarext
% directory.
%
% Written by A.Amaro (02-22-2007) and generously donated to xml_io_tools.
% This function is needed as a work-around for a bug in XMLUtils library
% which can not write CDATA SECTION nodes correctly. Also Xerces and
% XMLUtils libraries handle namespaces differently.
%
% Examples:
% % See xmlwrite examples this function have almost identical behavior.
%
% Advanced use:
% FILENAME can also be a URN, java.io.OutputStream or java.io.Writer object
% SOURCE can also be a SAX InputSource, JAXP Source, InputStream, or
% Reader object

% Using the XERCES classes directly, is not needed to modify the
% filename string. So I have commented this next line
% result = F_xmlstringinput(result,false);
end

end
end
% SERIALIZATION OF THE DOM DOCUMENT USING XERCES CLASSES DIRECTLY
% 1) create the output format according to the document definitions
% and type
objOutputFormat = org.apache.xml.serialize.OutputFormat(source);
set(objOutputFormat,'Indenting','on');
% 2) create the output stream. In this case: an XML file
objFile = java.io.File(result);
objOutputStream = java.io.FileOutputStream(objFile);
% 3) Create the Xerces Serializer object
objSerializer= org.apache.xml.serialize.XMLSerializer(objOutputStream,objOutputFormat);
% 4) Serialize to the XML files
javaMethod('serialize',objSerializer,source);
% 5) IMPORTANT! Delete the objects to liberate the XML file created
objOutputStream.close;
