I saw today that Microsoft released an XML editor (even though it looks like it was released on 9/1). I'm glad there's finally a tool out there that allows you to see xml in this format and apply transformations. I'm sure that a lot of developers have had a tough time in finding free tools that work good in the past. I downloaded it today and gave it a whirl opening and viewing an xml file I was modifying. Its very useful - although there's one view that I wish the tool had - the actual xml that I would be able to edit, and I suppose I can still use notepad or visual studio, but I was thinking this one be the one tool that would have it all. The xml transformation piece is worth the download alone.
