Is this what are you looking for?

$("heading:eq(1)",data).text();

As you can see here in the doc http://api.jquery.com/jQuery/ jQuery() (same as $()) receives second parameter "context", in your case this will be data and jQuery will search in this context instead of your HTML/DOM.

insomniac's reply is, I believe, not quite correct, because :nth-child(2) returns every other selector, not just the second. The selector you need is :eq(1). This gets the second item to match the previous selector:

$(this).find('heading:eq(1)').text();

Note that eq uses 0-based indexing (i.e. the first item is 0, the second is 1, etc).

See the jQuery API for more information: http://api.jquery.com/eq-selector/
