If it's data that accumulates and grows, extracting only the needed data into XML is pretty much a requirement. Databases employ indexes (b-trees and such) to make queries fast. XML does not. When you have a 1-million line XML file, you'll see how true this is...

the biggest XML file I ever had to style up (with XSLT) was about 1.5Gb. It was the 8-minute page load times that convinced the client to pursue a more viable storage strategy
