The Unknown OneNote Guy has created a quick and dirty OneNote 2007 Xml Viewer

I say quick and dirty because it comes with the following warning…

A few things to note about this application - I would not consider this a solid app. There was little if any design, no refactoring, and the User Interface portion was beat into submission with a stick - sorry I am a Web Developer and more behind the scenes then out in front. Big disclaimer here - please don’t use this in your mission critical applications. You get what you pay for in this application. It is meant for entertainment purposes only!

Despite this, I think it is awesome. Trying to get access to the XML in OneNote is not as easy as the rest of Office 2007 and this is a great starting point for developers wanting to get familiar with the raw data. Hopefully it will spur some more import/export tools.
