I understand that I can always iterate down the DOM tree and check every element for a data field and if the value is correct but I would like a cleaner solution. For example

    <div id=theDiv>

       <div>

         <span data-num=3 ></span>

         OTHER HTML

       </div>

       <div>

         <div><span data-num=23></span><div>

         OTHER HTML

       </div>

       <div>

         <span data-num=3></span>

         OTHER HTML

       </div>

    </div>

Is there a jQuery one liner to find all spans with data-num=3? I know I can find all spans by

  $(#theDiv).find(span).each(function(e) { ... });

but I would like something like

  $(#theDiv).find(span > data-num=3).each(function(e) { ... });
