I have more domplate goodness for you. First of all keep in mind that domplate only works in Firefox right now. I will be making it cross-browser soon! Also, it requires some plumbing code if used outside of Firebug that I will be removing as well.
This post is about the variable substitution and variable formatter functionality in domplate. I will start by showing you what you can do with the domplate implementation that is shipped with Firebug and then tell you about a little enhancement I made on my own copy.
