XOM API for Processing XML with Java

[Wolfgang Hoschek <whoschek AT lbl.gov>]

I admit, it was a poor example. How about compound calculations where 
the output does not reflect list size? Say, growth of revenue wrt. last 
year's quarter? Might lean a little towards XQuery.

In any case, I recently added an efficient convenience method for 
common cases with which one can do the same thing if desired:

int count = XQueryUtil.xquery(contextNode, "//*").size();

It is just a little convenience method and does not obsolete the more 
powerful API underneath.
