To clearify; my JSON script does not create an instance of an IE browser, nor create instances of the DOM or similar. It uses wscript.exe to access window's jscript engine, and various native libraries for making web requests when necessary.

As far as COM+DOM, this is QUITE difficult to do without creating a full instance of IE and then only limited information is available. I've tried a few times to make an html parser using an IE browser instance and there's roadblocks all along the way.
