Instructions:

1. Just click the load button and locate an XML file (or use this)
2. Click Attributes or Children to view the node attributes and sub-nodes respectively
3. Enjoy!

I’ve tested it with a relatively basic web.config so it should work with _almost_ anything. Right now you only get 4k worth of pixels to work with since I still have to get the control to tell the DOM to expand. If you run into any issues please post in the comments.
