Of course, you must have been living under a rock somewhere if you haven't heard about this article from one of the guys that helped develop XML - stating that XML Is Too Hard For Programmers

"Too hard?" you say....well, listen to his main argument: there's no language that's optimized for working in XML. Basically, there's no language out there that, based on its own internal functions, can read/write/edit XML quickly and easily. All of the languages out there (including PHP), are forced to either use just the building blocks to create these tools, or have tools that just aren't mature enough.

Obviously, this article has a lot to say, considering who it's from. He's right, though - we, as humans, have to do way too much interpreting on the XML's part to even be able to use it. But, I can bet you that language pieces like he talks about here aren't too far off...

Thanks to PHPEverywhere for the link.
