Rowan Bunning, the product manager of XML WithStyle has just put up some new and interesting material on Software WithStyle's XML editor. A beta will be available for trial shortly and this product information is a bit of a teaser.
Take a look at the XML WithStyle website for lots of interesting information and to sign up to be notified when the beta is released. And check out the Product Overview (or the really good PDF version of it) to get a better feel for how it all fits together.
Honestly, editing XML has never been simpler - in fact, you can completely forget there's even any XML there.
I write to my blog using the same technology that powers XML WithStyle - it's in Bottom Line, the blog posting tool that comes with Bottom Feeder.
