2017-09-22: Checked xpaths for granted, made corrections for mistakes in the text file and McNair.
To-do notes: For the assignment file in E:\McNair\Projects\SimplerPatentData\data\examples, list the XML and an example for 1 instance of every node of information. Don't need to list repeats,just every unique xpath with its corresponding example. pgs 27-28 of https://www.uspto.gov/sites/default/files/documents/USPTO_Patents_Assignment_Dataset_WP.pdf have good definitions.
