We now have an example of Open XML document generation using Ruby on Rails here. This is a reimplementation of a previous sample originally written in C#. The new sample, as were the earlier samples, generates a fancy patient report in Word from data contained in an HL7 XML data file, similar to a mail merge.

As an aside, now we have the three implementations of the same sample, showing just how open “Open XML” really is:

• C# implementation is here 
• Java implementation is here 
• Ruby on Rails implementation is here
