XML and Sql Server 2005

I have a problem that I want to solve in the best possible way. The thing is, I created a schematic that looks like this:

Now I don't want to put the entire XML document on one line. At least I think it's bad. I would like to move "poslovnica" (contains several "poslovnica") in one table and "lift" in others ... And is it better to keep each "poslovnica" in one row in the Poslovnica table or have all the "poslovnica" elements in the same row ? What about uniqueness, since SQL Server does not support a unique xml datatype, I saw that you can use triggers and functions, is there any other way? Also, if I break the xml document and get poslovnice in one table and pick them up in another, how do I get to show that vozilo belongs to poslovnica, should I put the poslovnica id in each drove in the xml, or should I refer to rows in SQL Server?

Or could you recommend any other database?

Thanks a lot, I'm sorry if I wasn't clear enough :(!
