When it comes time to work with XML the first company that comes to mind is Altova. The Missionkit suite is to XML what Visual Studio is to C#. At the core of this suite: the hands down (imho) best XML IDE Altova’s XMLSpy. 
I’ve been planning this blog entry for some time now and the reason that I kept putting it off was because I honestly didn’t know where to start. I was going to list my favorite features, one by one, but when I was organizing my thoughts I had a list and didn’t seem to end… So in order to to prevent this from becoming like one of Holden Caulfield’s rants I will cut this short and simply make this statement: If you are working with XML, in any facet, you should be using XmlSpy, if you’re not, your wasting time.
