Predicates can be chained

The Hamlet file actually has lots of <ab> elements in speeches as well as <l> elements, so this line count stuff is not a true reflection of the length of speeches. It might be worth telling the students there’s something wrong with it, and asking them to look at the XML source to see if they can figure out what it is. Then you could amend the first item in this slide, and some of the ones in the next slide, to account for this.

Simplified XML tree

Classic simplified tree diagram of the limerick Warp Speed, Ms Bright! that uses a dashed curved arrow to represent the link from the <note> to the <term>, and a dotted arrow to indicate the link from the <ptr> to the Wikipedia article. It is simplified because it does not contain attribute (or text) nodes, and is missing an <l>.
