How can I loop though form responses?

I'm trying to build a form notification so that when ever someone submits a form an email get's sent to a site administrator. The email needs to contain all of the user's responses.

The following blog post shows how to generate the email but not how to add the user's responses to the email.

I found the answer here Dynamically displaying Form Responses with Field Titles.
