This code uses the Ruby gem 'syntax' to create an XML file containing the HTML tags around the code, which is then transformed into an HTML file. The working example was first built using coding examples from Howto format ruby code for blogs [wolfman.com] and Formatting Ruby and HTML code for blog posting [blogspot.com]
