The assert_xpath plugin wraps that up in this convenient method:

    class REXML::Element
      def inner_text
        return self.each_element( './/text()' ){}.join( '' )
      end
    end
...
    def test_absolve_breaks
      a = REXML::Document.new("<Site>123 
street<br/>amstown<br/>amserland</Site>")
      assert_equal "123 streetamstownamserland", a.inner_text
    end

Come to think of it, that's not terribly programmer-friendly! Let's upgrade 
it a little...

      assert_equal "123 streetamstownamserland", a.inner_text
      assert_equal "123 street\namstown\namserland", a.inner_text("\n")
...
  def inner_text(interstitial = '')
    return self.each_element( './/text()' ){}.join(interstitial)
  end
