How large are the documents you're trying to build?  If they are small,
I recommend faster-builder:

  http://github.com/codahale/faster-builder/tree/master

Unfortunately its speed diminshes a lot as the number of nodes increase.
If the documents are large, you should try Nokogiri's builder.  I found
it to be faster for larger documents than faster-builder.

Here is my benchmark:  http://gist.github.com/14196

Here is some example builder code:
