== XML Editors ==

* XMLSpy - http://www.altova.com - This is probably the best XML editor out there, and there is a free version available. Unfortunately many of the things that make it so great are not present in the free version. There is a 30 day trial of the good version.

* Liquid XML Editor - http://www.liquid-technologies.com - Another good commercial xml editor that is available for a 30 day trial period, includes intellisense, validation and other important features.

* XMLMarker - http://symbolclick.com/ - Completely free and pretty decent tree based XML Editor -- probably the best of no-cost editors out there.

* Peter's XML Editor - http://www.iol.ie/~pxe/ - Another decent, completely free XML editor.

* TextMate -http://www.macromates.com - Me boss (Mister Fizzwidget) tells me I should be lettin you know 'bout his favorite editor, wit' all kindsa good voodoo for XML, Lua, and other lingos you be programmin' and scriptin' with. It be good and hackable, too, so it be easy to add support for other languages: Lua support be a third-party addition, which you can get from here: http://phrogz.net/tmp/Lua.tmbundle.tar.gz - TextMate's lua support bundle is also available now in the subversion repository of bundles hosted by TextMate's author:  macromates.com/wiki/Main/Bundles/
