Hi Eric,

In XPath, each `/` says to go down the XML tree hierarchy once, and a 
double slash (`//`) says "I don't care how far down I have to go from my 
starting position, get me all descendants that match the next thing I 
specify". So you can use a slightly more explicit XPath to find what you 

`//teiHeader//author` -> "Go to <teiHeader>, then get all its descendant 
`//text//author` -> "Go to <text>, then get all its descendant <author>s"

To get counts in pure XPath (you'll have to check if your parser can 
handle functions like this), you can use the count function:

`count(//teiHeader//author)` -> "Get a count of the results for 

Hope this helps!
