additional comment:

after better reading code, see want receive author name (which know, because in received xml).

there way you

use data-* attribute in html

<select class="songs">     <option value="1" data-author="author name 1">i left heart on europa</option>         <option value="2" data-author="author name 2">oh ganymede</option>         <option value="3" data-author="author name 3">kallichore</option> </select> 

and catch using jquery

$(".songs").change(function() {     var author = $("select option:selected").attr("data-author");     $(".author").text(author); }); 

note

you need include jquery html.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
