Feasible to check out XML file from QuickLook?

How can I use QuickLook to check out XML file? I just want to quickly check out the contents of a file and don't have to open it in a format that can be subsequently modified, such as in TextEdit or Vim or whatever other editors out there. I even don't like to open it in Xcode using drag and drop - just want to push Space and glance at the contents there.

And it looks like QLStephen doesn't support XML/plist files. So is there any alternative way to glance at it from QuickLook?

I use OS X 10.9.2.

When installing Textmate 2 you get QuickLook support for a bunch of data files including XML, Json etc.
