Thank you for the solution
I never thought of that. I think I could use what you have suggested in cases where I transform the xml with jstl and just need the count of certain node sets.
I tried XTags, and it has a rich set of XPath capabilities, I was able to do something more complex like this <xtags:valueOf select="substring(/Books/Book[${item_position}]/BookTitle, 0, 50)" /> inside the JSP
I wonder if one (JSTL XML Tags) is better than the other(XTags) performance wise, but may be they are just different tools with their own purpose.
I'm not sure that XTags was ever officially released. I assume you're using
one of the nightly builds. The Standard taglib is an implementation of JSTL
which has been officially released for both JSTL 1.0 and JSTL 1.1.
Your original code actually appears to work with Standard 1.0.6 (JSTL 1.0).
To support XPath, Standard 1.0 uses Jaxen/SAXPath while Standard 1.1 uses
Xalan. It's likely there's a bug in how Standard 1.1 is using Xalan to do
its XPath evaluation. I believe XTags uses dom4j.

I searched for a solution for this but couldn't find an answer.
I'm trying to count the number of book nodes from the xml below:
Book Title 1
Book Title 2
Book Title 3
Book Title 4
Book Title 5
I tried using XPath's count function, inside the JSP page, but it gives 0 instead of
5 - (the number of book nodes)
Is it possible to obtain the count of a node set inside a JSP or do I have to
first transform the source XML into another XML which obtains the count and
then read the count from the second XML file?
Hm, this works though (Standard 1.1.2):
