Which part of the text I quoted do you not understand?

"REXML stream parsing requires you to supply a Listener class"

Do you know how to create a class in Ruby? It's just:

class MyListener
end

"When a tag is encountered, the stream listener's tag_start() method is
called. When the tag end is encountered, tag_end() is called. When text
is encountered, text() is called, and so on, until the end of the stream
is reached"

So, add those methods to your class, just like it says.

class MyListener
  def tag_start(*args)
    puts "Got tag_start with #{args.inspect}"
  end
  def tag_end(*args)
    puts "Got tag_start with #{args.inspect}"
  end
  def text(*args)
    puts "Got text with #{args.inspect}"
  end
end

The rest of the code you need is directly given in the example.
