Recently I encountered a situation where I wanted to move some content to a new WordPress installation (not this one) from a piece of forum software that hadn't been attended to or upgraded in, you know, half a decade or so. Normally I would hit Google to try and find a solution for a problem like this, but I figured my particular circumstances were sufficiently esoteric that I could likely sort it out more quickly on my own. And it became a convenient opportunity to test and flex some basic XSLT muscle memory.
