Rexml/document problem

[code]

<?xml version="1.0"?>
<a>

  <b prefix="A" num="1" />
  <b perfix="B" num="2" />
  <b prefix="C" num="3" />
  <b prefix="D" num="4" />
  <b prefix="F" num="5" />
</a>
[/code]

This is my xml file data. There include several <b> in the xml file. i
can read the 1st data:

puts root.elements["b"].attributes["prefix"]

Now i cannot read the <b> 1 by 1. How can i read the <b> and write the
output is:

"A"
"B"
"C"
"D"
"E"

REXML::XPath.each(root, '//b') do |node|
    p node.text
end
