Seems XML is having a revival on HN so I'll just repost my XML editor:

I would love to know what people think of my XML node-graph/tree editor I made before JSON became mainstream (my excuse): http://rupy.se/logic.jar

- You link/unlink nodes (I called them entities! Xo) by right-click-dragging between them.

- You copy stuff by right-click-dragging to an empty space.

- You delete by grabbing something by left-click-holding and pressing the delete key.

- Oh, and nodes are completely tree structure expandable, just drag-drop attributes on nodes and nodes inside nodes.

(I know, not super intuitive; but very handy once you know about these.)

The editor uses lightweight rendering so you can have a ton of elements with good performance.
