I did go through the answers there. What i want to do is actually different. Instead of converting the Latex file to XML using tex4ht or some other thing i want to directly redirect the output to XML instead of DVI. tex4ht basically creates a DVI file and then processes it to do the conversion.I just to avid this step and let Luatex redirect the output to XML as it can do in case of Context

Thanks and Regards
