It's a good start, but you'll get each element processed N times,
where N is the number of that elements with that name.  In other
words, if you have two <apple> elements, you'll get each of them
processed twice.

In other words, this is a classic grouping problem... find the
members of a group but eliminate duplicate processing.
Look at http://www.dpawson.co.uk/xsl/sect2/N4486.html for help,
or read ch. 10 of Tennison's "Beginning XSLT".
