ASPhere is a freeware utility primarily intended for creating and modifying configuration files for ASP.NET. But they are not only web.config files ASPhere can work with, you can use it for viewing and editing normal XML files and plain text files as well.
If you ever tried to create web.config files, you would definitely agree with me that modifying of these files can be time-consuming work. This tool should help you to do this in a more comfortable way.
It offers you a graphical user interface for editing XML-based files, a text editor with syntax highlighting, intelligent contextual help and other useful features such as comparing files.
