It's for viewing XML only. And all info is not refined. It needs more work, but this is just to show, that i am capable of making it

Ahhh... BTW this program has one glich witch i was to lazy to fix: when you load XML file, resize window a little to see the xml tree.
V1.0- Ok, i think i will call this as version 1 because it provides basic viewing capability and it is more accurate than blueprints. Fixed some bugs. No editing possible now. And you must restart program every time you open different XML file.
V1.1- Cleaned a little; now you can open as many files as you want (there will be tabs in future to support multiple files editing at same time). Removed colors until i figure a way to do it better. You navigate with right mouse button clicking once, and edit window (witch still doesn't edit) popup after pressing twice with left mouse key. Now i will start working on editing.
V2.0- Here it is

V3.1- Rewrote it almost from scratch with NetBeans GUI assistance:
[*] Tab support (just open as many files as you want).
[*] Edit and Delete elements (will improve GUI soon).
[*] Much better parsing method provides easy deleting and addings functions (adding still not done).
BEWARE - make backup of XML before you test. Because still didn't add feature witch asks if you want to overwrite any files.
