Create a Table of Contents for Blogger posts based on atom or rss feeds

This is a Javascript code that generates a table of contents based on your atom or rss feeds. It organizes the post titles based on labels. I use this script for my categories posts. All credits goes to Abu Farhan, the source of this Javascript.
