Almost certainly, the problem is that the document has a default namespace.
You need to identify the namespace in the XPath query.

This puts 'NA' in the first week of the year.

Dear Carl,
I think that the following does what you want:

they have the same precedence as `*`

Hi all!
I've written a handy script that uses a for loop to allow me to generate a
large number of figures and statistical outputs for a large dataset.
I am using indexing to retrieve a species name for the title of my graphs-
which worked fine. However, I need to italicize these species names.
I have a very large dataset with three variables that I need to graph using
a scatterplot. However I find that the first variable gets masked by the
other two, so the graph looks entirely different depending on the order of
variables. Does anyone have any suggestions how to manage this?
This code
