To expand on what I just said,

	emacs *.xml

opens all the xml config files. Then you can write editing
macros in emacs and step through each file pretty quickly.
Then you make sure the machines in question are unloaded
before you reload the new config and start them.

Depending on the editing complexity, you might use
sed or rpl to do it via a shell script.
