iTunes RSS feed parser
I cobbled together a parser for the iTunes RSS feed which renders the feed as HTML suitable for inclusion into a web page.
I made an effort to generate HTML in a manner that one can apply a style sheet to it and change the layout and appearance of it in a flexible manner, rather than using some sort of template mechanism. CSS is, unfortunately, both hard and in most, if not all, browsers generally broken, so it's not a perfect system, but I got it working well enough to render the page how I like it, so that's good enough for now. :-)
