Well, I guess you have to balance elegance & expandability vs raw
performance. Not an uncommon trade-off ...
But, that being said ...
Creating XML from an RDBMS is very quick, particularly when you
do it using straightforward non-XML code.
True, XML->HTML is not as quick as would be liked, but it
again depends on the nature of the work. If your HTML needs
a lot of complex cross-linking, tables of contents, navigation
bars, etc, then doing this straight from the RDBMS can be
a real bitch.
Also, the speed of processing XML will depend on the tool.
Have you considered using something like Omnimark, instead
of DOM, etc?
Just some more food for thought,
