I <3 XML/XSL and CSS

I am falling in love with various markup languages today, thanks to the W3C's CSS reference and the XSL reference I posted about a few days ago. I'm working on a bunch of reports for work, and the raw report data gets spit out in XML format. Right now I'm using CSS and XSL transformations to spit out a bunch of different report formats, and, let me tell you, I never really *got* why these technologies were so wonderful until now. I mean, I got it - separation of style from content, yadda yadda yadda - but actually using the stuff on such a large scale instead of just on some personal project really drives the point home. So wonderful!
