How many times have you had the need to mangle an XML file from the command line? If you're like me, you'll quickly hit a dozen or more times before breakfast. But that's mainly because I'm so behind in my work. Anyway, this is the home page for xmlsnipe, a nice little program to mangle xml files.
For more information see the sourceforge page for the project. I've recently released the 0.0.1 version of the software, which is basically my first release. I don't know what it says about the quality of the software or what not. Download, read the docs, it will tell you what to do.
