XML Spy Rocks

I have been using XML Spy for building small site of mine. It?s really nice program, I have tried XML Spy few times before but I felt that there is to high edge to learn again another tool but now I finally got into it and it is really nice.
I use XML Spy as a content management system. I have my data physically on my hard drive as small xml files and then in a other folder I have site configuration as another XML files. Then by using XML Spy project I compile XML in to XHTML just by pressing F10 little bit like in VS.NET you compile project by pressing F5. Neat :)
