I think that the answer is "probably not." After all, the SQL based view 
is usually generated *by the database* over information under the 
control of the database. That's why it isn't easy to build a SQL view 
over a heterogenous system. (or if it is, I don't know how)

XML is "fast enough" for the tasks that it is demonstrably successful at 
and probably for many that it hasn't been used for yet. It probably 
won't be fast enough for everything and then you may have to make some 
engineering tradeoffs: give up XML's flexibility and ease of composition 
but gain performance. Engineers trade off flexibility for performance 
every day!
