Ok, I've read a couple books on XML and wrote programs to spit it out and what not. But here's the question. Both a comma delimited file and a XML file are "human readable." But in general, the comma delimited file is much easier on my eyes than a XML file; the tags typically take up as much if not more space than the data. This just seems to obscure what I'm reading and the format can take a page to contain the same information that you can contain on a single line of text in a comma delimited file. And a comma delimited file is significantly less complex to parse. So the real question is why XML? Just because all the cool kids are doing it?
