Good day Monks,

I am really having a hard time understanding the XML::Twig module and how to actually use it. I am hoping someone could give me a jumpstart on how to extract attributes and values from any level of the xml tree. I have fumbled and fumbled with different trival examples found but I can't seem to understand the real logic of what I am reading. I would with all sincerity appreciate any help that could be provided. I think if I could get a working example of code against the small snippet of xml defined below I might actually catch on and understand how to walk down any twig and extract the attrib/values regardless of how deep they go. Please pardon my short-comings with regard to OOP.

Many thanks,
Danny
