Transforming word Doc in to an XML?

I searched in msdn abt how to Transfer word Documents into XML or XSL-FO? From that I got this linkTransforming Word Documents into the XSL-FO Format, here they given all the procedure how to do that.Its manual one. But i wanted these work to be done by program itself. Can u please help in this. So far i did something like

Microsoft.Office.Interop.Word.Application word =new Microsoft.Office.Interop.Word.Application();

Microsoft.Office.Interop.Word.Document doc =new Microsoft.Office.Interop.Word.Document();

try

object filename =@"E:\Share\docgen\Word2003\TestResult\All_Classes.doc";

object tFileName =@"E:\Share\docgen\Word2003\TestResult\All_Classes.xml";

doc = word.Documents.Open(ref filename,

ref missing,ref missing,ref missing,ref missing,ref missing,

ref missing,ref missing,ref missing,ref missing,ref missing,

ref missing,ref missing,ref missing,ref missing,ref missing);

object format = Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatXML;

word.Application.XMLNamespaces.Add(@"E:\Share\docgen\Word2003\Test\note.xsl",ref missing,ref missing,true);

word.ActiveDocument.SaveAs(ref tFileName,ref format,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing);

but it is throwing an exception as "Bad Command" Because Appl.xmlNameSpaces.Add is taking xsd as input but i was specifying xsl, because i want to apply transformation (.xsl) to doc. How Can i Do that
