As I'm trying to catch up on my blog reading, I just ran across a post from Roy Osherove: “TopXML releases the System.XML reference online”.

I wish I would have read this post a few days ago, because I was struggling with some Xml code...anyway, this is a great site.  The code formatting could be better, but at least they have sample code.  I hate firing up the MSDN Library, searching for something and then finding NO sample code.  Grrr.
