Xml?

What exactly is XML? I've found a few resources/demos etc. but they all asume prior knowledge on the subject?! What is it, and what is it used for?

Thanks. Laterz

XML stands for EXtensible Markup Language

Thanks. That site cleared a few things up. :)

I've been using the tut at xml101 too, but I hate using online tutorials- especially in a bandwidth-challenged environment like I have.

I'd really like a book in pdf or similar so I can print it and read it wherever I might be, like in the shower.

Anyone got any other addresses please?
