I don't think you can change an attribute name but what you can do is :

• get all the tags with a title attribute;
• foreach of them, create a newTitleName attribute with the same value as the title;
• then delete the title attribute.

JQuery let you do that with builtin functions this way :

/* get all  with a "title" attribute that are testingCase
then apply an anonymous function on each of them */

$('a.testingCase[title]').each(function() {   

    /* create a jquery object from the  DOM object */
    var $a_with_title = $(this);    

    /* add the new attribute with the title value */
    $a_with_title.attr("newTitleName", $a_with_title.getAttribute('title'));

    /* remove the old attribute */
    $a_with_title.removeAttr('title'); 

});
