Much easier to read, much cleaner.

....which would be absolutely fuckin retarded since um, why bother with
the XML bullshit at all? I mean, if the shit is already *IN* the
database...have it get the st00f DIRECTLY from the database.
Essentially all you've done is create a rather deficient middle man.

....how would it be a nightmare? Just use PHP and have it directly
access a database and retrieve the data directly thus bypassing the
need for any XML. Like I said, XML is just a poor mans database.
Anything you're doing with XML I can do the same, directly, with a SQL
database. That's why XML isn't really all that important overall. It
can be handy in Flash in that you can write XML files directly without
having to go through a PHP file to write data into a database...but
the bottom line is that there are EQUIVALENT solutions that can
achieve the same ends (extra code or not) and because of that, it's
not of "life or death" importance. With something like Flash...well
shit, if there was no Flash, half the gawd damn content would just be
fucking GONE because THERE IS NO equivalent. The closest you can get
is Java...and even it comes up short as far as video playback
capabilities amongst other things. The most IMPORTANT web technology
is the one that HAS NO REPLACEMENT. There's replacements for PHP,
there's replacements for XML, there's replacements for pretty much
everything...EXCEPT for Flash.

>that's easier to follow. Bet you can't :)1
Sure I can, take whatever code you said was taking entries from a
database to create that XML page and just modify it so that it'll send
that data directly to the Flash st00f. Your trying to imply that:
Flash -> PHP -> SQL Database -> XML -> Flash
is somehow faster than:
Flash -> PHP -> SQL Database -> Flash
It's not and your way would actually take MORE code and overall would
actually be SLOWER. *shrugs*
The only real advantage that XML has is in creating kind of disposable
databases in order to cut down on the processor consumption that comes
from accessing/searching/sorting through a SQL database. Essentially
you can have Flash just pick up the XML file and let Flash do the
accessing/searching/sorting client side rather than server side...the
DISADVANTAGE to that however is that you wouldn't be getting "real
time" data. Well, you could, but if you had it setup that way you
wouldn't NEED the XML at all, it'd just be consuming more resources.
In some situations with EXTREME server load it might make sense to
have a server side app that will create a new XML file every few
seconds, that way it's like the database is only being continuously
accessed by a single person rather than being continuously accessed by
dozens all at the same time.
Again though, if the technology was history and simply ceased to be
you could STILL achieve the same ends (slower and more resource heavy
or not) which is why it's not the MOST important.
