This post was written as I was still exploring resources and trying to suss out a learning path.
One of my technology related goals for professional development is learning how to work with and transform XML. Usually my go to resource for coding related topics is Codecademy, but sadly they have no resources here that I can find. Instead, Columbus Metropolitan Library offers Lynda.com access to anyone with a library card, a wonderful service. First up is the XML Essential Training course.
