Does this help you?

require 'rexml/document'
include REXML

d = Document.new <<ENDXML
<root>
   <foo>Raw text</foo>
   <foo>Raw text2</foo>
   <foo>AA <bar>Nested Text</bar>ZZ</foo>
</root>
ENDXML

p XPath.match( d, '//foo//text()' ).collect{ |textnode|
   textnode.value
}
#=> ["Raw text", "Raw text2", "AA", "Nested Text", "ZZ"]

class REXML::Element
   def inner_text
     self.each_element( './/text()' ){}.join( '' )
   end
end

p XPath.match( d, '//foo' ).collect{ |foo|
   foo.inner_text
}
#=> ["Raw text", "Raw text2", "AA Nested TextZZ"]
