Is there a XML editor similar to Inkscape built-in editor?

Question

I have been looking for a "perfect" XML editor, and today I realized the one used in Inkscape is exactely the way I would want, because:

• It has multi-panel (tree, attribute-list, and value text-box);
• Folding and highlight;
• The tags and XML syntax are kept invisible (and so protected from typos)

You can see what I mean here:

The only problem is... IT IS PART OF INKSCAPE, ONLY!

Does anyone know a similar program for standalone use, or a way to use that editor independently from inkscape?

Answer 1

It may not look nice, but I use gedit for all my programming needs. It's really bare-bones, but it has tons of plugins, so maybe you could find (or write) a few to suit your needs.
