xml2.xml:
---------
<?xml version="1.0" encoding="iso-8859-1"?>
<classmates>
  <friend>
      <name>Jane</name>
      <phone>123-4567</phone>
  </friend>

  <foe>
      <name>David</name>
      <friend>Tom</friend>
  </foe>

  <friend>
    <name>James</name>
    <phone>666-6666</phone>
  </friend>

</classmates>
------------



require 'rexml/document'
include REXML

f = File.new("xml2.xml")
doc = Document.new(f)

names = XPath.match(doc, "//friend")
puts names.length   #3

addresses = XPath.match(doc, "//addresses")
puts addresses.length   #0
