Subject: [ruby-talk:27604] REXML: problem with xpath

hello
I just downloaded the newest rexml (1.2)

I have the following xml document:

---
<programming_languages>
  <language oop='yes'>
    <name>
      Ruby
    </name>
    <creator>
      Yukihiro Matsumoto
    </creator>
  </language>
  <language oop='yes'>
    <name>
      Python
    </name>
    <creator>
      Guido van Rossum
    </creator>
  </language>
</programming_languages>
---

and the following ruby code:

---
require "rexml/document"

include REXML

doc = Document.new(File.new("lang.xml"))

doc.elements.each("//language/*") { |element|
        print element.name, "\n"
        print element.text, "\n"
}
---

the output of the programm is empty.
it must be a problem with the xpath-expression
//language/*
I am not an xpath guru, but I think this is valid (according to my books)
it should return all child elements of any "language" elements of the 
document.

I think, this worked with older versions of rexml

please let me know, if I made a mistake, or the problem is in REXML
although I think, that the error is with me.
