Subject: Help needed with rexml

I've been struggling to properly parse some XML with rexml. I will fully
admit my XML ignorance in advance. It would be easy enough to parse
this with a regular expression instead, but I would prefer to use the
right tool.

Here's a sample XML response:

<?xml version='1.0' encoding="iso-8859-1" ?>
<methodResponse>
  <fault>
		<value>
			<struct>
				<member>
					<name>faultCode</name>
						<value>
							<int>5</int>
						</value>
				</member>
				<member>
					<name>faultString</name>
				<value>
					<string>system error (nologin)</string>
				</value>
			</member>
		</struct>
	</value>
	</fault>
</methodResponse>

However, I can't anything useful out of it. For instance, I've been
trying something like this:

require 'rexml/document'

file = File.new("test.xml")
xml = REXML::Document.new(file)
xml.elements.each { |i|
	i.texts.each { |t|
		puts "Class: #{t.class}"
		puts "Value: #{t.value}"
		puts "String: #{t.to_s}"
	}
}

This doesn't print anything useful for the class. Where am I going wrong
with this? I've been digging through the documentation but I'm must not
getting it.

For what it's worth, I can parse this in perl easily enough (which
suggests to me the XML is valid):

use Data::Dumper;
use XML::Simple;  # AKA "XML For Idiots"

my $ref = XMLin("test.xml"); # A file containing the XML above
print Dumper $ref, "\n";

I can then use the results to figure out how to dereference $ref to pull
the error information returned by the server.
