Nokogiri's NodeSet implements Enumerable, and much of the Array interface,
so you should be able to treat it much like you'd treat any Ruby Array.

For example, to remove the first node in a NodeSet, simply use
`nodes.shift`. To remove the last node, use `nodes.pop`. Etc.

Just a note, that the above code removes the first node in the NodeSet from
its document. Not what you want.

Best of luck.
