XML editor

do you know Clip XML Editor ?
it's a new xml editor (as you probably already guessed ) entirely written in
Java.
it has somme cool features like error detection, validation...
The important thing to notice si that it's a visual editor (you don't have
to write code, all is user-friendly : you click on a button in the toolbar
and that writes you the code for the action you wanted to make )
The real problem is : it's a 100$ shareware !
Has someone already tried it?
