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
need:
`//teiHeader//author` -> "Go to <teiHeader>, then get all its descendant
<author>s"
`//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
`//teiHeader//author`"
Hope this helps!
Best,
Ashley

I have an XPath question, and more specifically, how can I determine the number
of author elements found an a TEI header?
I would like to create summary files similar to the files created by the late
Sebastian Rantz and found on GitHub. [1] I can easily determine the number of
author elements found in an entire TEI file with a Perl-esque XPath statement
similar to this:
$parser->find( “//author" )->size
But I’d like to know how to limit the finding of author elements to only the
teiheader or text elements.
