Recompiling go language  code during development is bit annoying task. But there is an package for that. Actually I found at least 3:

Exploring [The Go Language][1] is so much fun. Everything is brand new, and different then any other language. This time I’m going to show quick snippet which shows how to read JSON object with unknown structure, and map elements to something like hash table.

The only problem with running Gokogiri is that it uses libxml2 which is not a huge problem on Linux based systems, but on Mac OS X you have to install it via homebrew
brew install libxml2
