xml syntax highlighting breaks liquid processing

[stoicflame]

If you attempt syntax highlighting for xml, e.g.:

<some example="xml/>

Then processing fails:

Liquid error: Requires a Node, NodeSet or String argument, and cannot accept a NilClass. (You probably want to select a node from the Document with at() or search(), or create a new Node via Node.new().)

Try installing pygments.

Thanks for the tip!

I'm getting the same error on Heroku, is it possible to disable syntax highlighting in order to avoid this error?
