For those that say .Net isn't fast, take a look at this:
Parse All Test Video.
Yeah that's right, it parsed every Xml file in the default directory into the objects (the actual things you edit before hitting save) in less than 16 seconds. My rig is kinda beefy though, so may just be the speed of my computer being that fast, you will have the excuse the choppy video, it simply couldn't keep up with my screen, even at the highest/lowest quality settings of the recording software. Didn't upload the source yet, still have a few more changes to make to the class library, like the ability to save each window to it's respective Xml file, and gotta add debug spews to alot of the classes yet.
So it appears the actual speed factor will come in the editing studio and not the actual parser.
What you can't see in the video due to quality, is that the screen info and xml display boxes are flashing very rapidly, once for every 122 xml files.
