Re: Why does jackrabbit unsupport the count function in XPATH

[Marcel Reutegger]

I'm not sure if this is of any help, but if you are interested in the 
number of nodes returned by the query you may also use the 
NodeIterator.getSize() method. In jackrabbit this will always return a 
reasonable value, unless your query is //* then it will return -1.
