Excellent.
Remarks:
1. I couldnt activate find on element values.
2. could it implement microsoft xmlpad behaviour of showing sub-elements in the rightside?

Fast install, Load and Run.
Very convenient and fast to view complicated hierarchical xml file. Just what I need.

Wishlist:
1. Enable "Save as..." and "Find..." in xml_source sub_window.
3. Add 2nd view window to the left of main window, which will show same tree structure as the main window, but without the comments, so, that if an element has many comments and some sub_elements scattered within, whilst in the main window that shows the xml "as is", I have to scroll down to see is there are sub_elements, the 2nd lest window shows the structure "neto". An alternate option is to "switch" the main window between these 2 modes.

Loaded in seconds, started right up, showed me my data. Terrific little viewer. Thanks a bunch!
