I tried the below code:

require "nokogiri"
doc =  Nokogiri::HTML::Document.parse(<<-eohtml)
<html>
  <head>
    <style>
    span.fot { color: red; font-size: 120%; font-style: italic; }
    </style>
  </head>
<body>
  <div>
    <span>Corey,</span>
    <span>Yehuda,</span>
    <span>Adam,</span>
    <span>Todd</span>
  </div>
  <div>
    <b>Nobody,</b>
    <span>Jörn,</span>
    <span>Scott,</span>
    <span>Timo</span>
  </div>
</body>
</html>
eohtml

p doc.css("span:first-of-type").map(&:text)
p doc.css("span:last-of-type").map(&:text)
# >> ["Corey,"]  I expect here ["Corey,","Jörn,"]
# >> ["Timo"] I expect here ["Timo","Todd"]

p:first-of-type -> Selects every <p> element that is the first <p> element of its parent and

p:last-of-type -> Selects every <p> element that is the only <p> element of its parent

Then why nokogiri gives such unexpected output?

Could you add here a simple example to show how to use Class Nokogiri::XML::EntityReference::new method. The doc doesn't carry a single example on it. Your help on this will be must appreciated. Also to give some lines to say what this class stands for?
