Query on XmlConfigFile

I am using XmlConfigFile from as under

I was dissappointed not to find any Q&A in the ruby forum about this
Simple and Easy Ruby+XML utility.

For anyone who is using this please help me to solve the following

I am parsing an XML document and I need to extract the element values
and attributes.

I am tryin as per the above link under “Handling Sets of Configuration
Parameters” I could not store the values resulting Hash into a variable
so that it shall be printed using either puts or print. I mean to access
every element value or attribute into a unique variable.

Attached are my Script and XML File.
