Free lightweight XML text editor to include with an application

Question

Our application uses a XML configuation file. I thought that it would be nice to distribute some XML editor with our application, so that the user can conveniently edit the config file. Features should be:

• Small and lightweight (ideally, a small .exe that does not require installation),
• free, with license terms that permit distributing it with a commercial application,
• understands XML schemas (auto-completion, show validation errors).

Does anyone know of such an editor?

Answer 1

Notepad++ (free as in beer and as in free speech) http://notepad-plus.sourceforge.net/uk/site.htm

This fulfills most of your requirements; however, it only has tag collapsing and will not show validation errors or auto completion.

XML Notepad by MSFT is good, but it does not allow wide distribution. You may be able to get by checking installed apps for XML Notepad and, if it's installed, sending startup arguments to the app.
