XHTML Validator to RSS : Ben Hammersley: Oh my goodness, this is brilliant.
…I like nice to-do lists and automatic checking of my pages. So to combine the two, I’ve made a widget to create a XHTML Validation Results RSS feed from any page.
I now have an RSS feed of validation errors on my site, updated whenever I check it. The ingenuity of this is so great that it’s giving me a cramp.
