WORD-ML to FO-XML

I have a project where we are generating worddocument using WORD-ML. *At this point client also wants to havedocument generated in PDF. For this I need to convert my WORD-ML intoFO-XML. Do anyone know how I can do this. I can not write FO-XML fromscratch at this point. I just need a tool or some process which canconvert my WORD-ML to FO-XML.

Thanks.
