Selecting the next specified element?

Selecting the next specified element?

Hi,

When I click on my h3 tag I would like to do a replace on the next "dframe" element (not all "dframe" elements). I've tried the code below but it doesn't select the next specified element. I guess next() only covers the next sibling? Does anyone know a way of executing this?

$(".regionfulldublin h3").click(function() {
      $(this).next('dframe').replaceWith('<iframe></iframe>');


});

Thanks in advance!
