You can use REXML::Element#namespace if you are using a-la DOM API.

----------Example-----------------
require 'rexml/document'

xml = <<XML
<?xml version='1.0'?>
<a xmlns:fuga='foo'>
 <b>
  <c xmlns:fuga='hoge'/>
 </b>
 <d xmlns:fuga='bar'/>
</a>
XML

doc = REXML::Document.new(xml)

p doc.root.namespace("fuga")
p doc.elements["/a/b"].namespace("fuga")
p doc.elements["/a/b/c"].namespace("fuga")
p doc.elements["/a/d"].namespace("fuga")
----------Example-----------------

----------Output------------------
"foo"
"foo"
"hoge"
"bar"
----------Output------------------
