How can I Present WordprocessingML document?

Hi, 

In my project I need to present a read-only word document given to me in WordprocessingML format.

Currently I convert the WordML to HTML using XSLT but the resulting document is far from perfect.

Is there is something except MS Word COM component to present WordML?

I'm open to all .NET technologies, including Orcas.

Hope it's the right forum,

Thanks.
