Honestly, I'm not 100% sure yet.  libxml's huge and there's lots
there.  I'm still uncovering features and nifty ways of doing things.
My best guess is that it's basically a Schema/DTD for the DocBook
markup (ie, won't let you write a bad/invalid docbook document).

In this case, the contents of the node's child.  With the XML below
(and the amended example: sorry, was doing a little too much
copy/pasting from the rubynet test examples), it would produce:

Filename: uga
Mode: ble
Content: sweet


# Amended example
xd = XML::Document.file('some_xml_file.xml')
xd.xpath_find('/my/xpath/query').each do |node|
  puts "Filename: #{node.child('foo')}"
  puts "Mode:     #{node.child('bar')}"
  puts "Content:  #{node.child('baz')}"
end

# XML snippet
<my>
  <xpath>
    <query>
      <foo>uga</foo>
      <bar>ble</mode>
      <baz>sweet</baz>
    </query>
  </xpath>
</my>


node.to_s == node.child.content
