Subject: [newbie] REXML, each_element and XPath

Hi!

while playing with REXML I try to use each_element with an x-path
expression involving an attribute (doc/element/@attribute) but can't
get it to work this way (it works perfectly fine with both XPath.each
and each_element applied on doc/element without @attribute).

here's my test suite to illustrate this, is there some obvious mistake
that I cannot see ? I've read in older posts that each_element did not
recurse, would it be the explanation ?

any insight most welcome!

kind regards

Thibaut

require "test/unit"
require "rexml/document"
include REXML

class XmlTests < Test::Unit::TestCase

  # fail
  def test_each_element_with_attribute
	count = 0
	@doc.each_element("doc/element/@attribute") { |n| count = count+1 }
	assert_equal 1,count
  end

  # pass
  def test_each_element_without_attribute
	count = 0
	@doc.each_element("doc/element") { |n| count = count+1 }
	assert_equal 1,count
  end

  # pass
  def test_xpath
    count = 0
	XPath.each(@doc,"doc/element/@attribute") { |n| count = count+1 }
	assert_equal 1,count
  end

  def setup
	@doc = Document.new(<<EOF
		<doc>
			<element attribute="value"/>
		</doc>
EOF
    )
  end
  
end
