Not a chance. There is no such thing as a native XML database and

going to build a native hierarchical database you sure wouldn't use
the wasteful XML format internally to store the data.
And if you insist on using XML just because its so wonderful to use
17 characters to store the state <STATE>NY</STATE>, it will never be
able to compete with even the most immature relational engines for
pure speed. Maybe on example and toy sites, but never for anything
that needs to scale.
If I'm wrong, dinner's on me.
Which part do you have to be wrong about for me to get a free dinner?
I can already give you several existence proofs demonstrating that
there is such a thing as a native XML database:

http://exist.sourceforge.net/
A sourceforge project does not a phenomenon make. I guess when the
banks and airlines have our data in the XML files, and I don't mean a
few hybrid patchwork examples, I mean the hardcore permanent long-term
stuff as well as the transactional support for the reservations we're
making all day. When that happens, we'll start picking the restaurants.
More are coming.
