I want to use xpath to count occurances of certain node in xml document. What would I use? For ex: If I wanted to get second occurance of movie node I'd use movie[2].
How do I get total number of movie node occurances in document?

A:
Try count(//movie). See http://msdn.microsoft.com/en-us/library/ms256103.aspx for detail.

@KennyTM: `count(movie)` will get evaluate to the number of `movie` childs of context node. Also, why did you not cite specs but MS documentation instead?

@Alej: The spec doesn't have a clear example.

-1 because this is incorrect w.r.t. the question, "How do I get total number of movie node occurrences in document?"

Use count function. From http://www.w3.org/TR/xpath/#function-count
The count function returns the number of nodes in the argument node-set
So, in your case, this XPath expression:
count(//movie)
