      </book>
</library>

I am trying to create an xpath expression to count the number books,under <library> .. </library> using count() . But I couldn't figure out.

Any help in this regard?

What have you tried so far? Showing us what you've tried will help us understand better where your problem is.

In this case, you want count(/library/book). The query /library/book returns all of the book elements, which you should pass as a parameter to the count function so it can do what it does.

Are you using an XML editor that lets you perform XPath queries while you work? I've found it to be extremely helpful; I normally use XMLPad.
