Looking for DOM-independent JavaScript templating system works \w plain text.

Question

Is there a templating library/system/engine/technique written in javascript that:

• Doesn't screw up plain-text (non-html) templates ( like tabs and line breaks )
• But also works with HTML
• Doesn't have it's own DSL for loops and conditions (uses pure JS)
• Can be run server-side without the DOM

...and is open-source licensed?
