I wanted to let everyone know about this good Free XML Editor it's called Notepad++. You can get it here NotePad++ Info & Download

I've been using this program to edit EAW, FOC, CIV4, and I also use it to Hex edit.
Here's a list of features I know off the top of my head:
-Tabbed Browsing of Files
-Hex Editing
-Supports multiple programing Languages
-Has Syntax Highlighting & Syntax Folding
-Bookmarks
-Macro Recording & Playback

I hope you guys & gals enjoy this program.

Hmm... why should one use an editor ?
Any .txt editor is fine.
If the editor supports syntax check, then, yes, it would be a step forward.
