Write a file named hw5b.htm. This file should create a form with a select for a user to choose one of twelve astrological signs. The form should also have a button. When the user clicks the button, an AJAX request is made to a file named hw5b.php. This file will take the value of the select as a parameter, and produce a response that will consist of XML that contains nodes consisting of the astrological sign, the dates of that sign, and a brief horoscope. When hwb.htm receives the response, it should display this data inside a DIV.
