The w3schools tutorials are very helpful to me and usually give enough information to get started. I prefer a textual tutorial rather than pausing a video, rewinding it, and listening over again if I was unclear. The textual guides let me read/learn at my pace rather than the pace of the speaker. This was my first experience with XML and it showed me just how flexible it is. Rather than being restricted to the preconfigured tags of a language like HTML, XML allows me to categorize items as I wish. This freedom does create the problem of whether certain lines should be an element or an attribute. As is usually the case with an organization scheme, it depends on how one will use the information. There is some gratification in thinking through whether to write an attribute or an element and its justification. Here is the XML scheme that I wrote for practice.
