This question seems to be ambiguous.

I'll try with my interpretation of the request.

def do_something(data)
   puts "Found! #{data}"
end

a = { 'x' => 'test', 'y' => 'foo', 'z' => 'bar' }
a.each { |key,value| do_something(value) if key == 'x' }

This will loop over all the key,value pairs and do something only if the key is 'x'.
