jQuery loop through Child divs

<div id="ChosenCategory" class="chosen">
   <div class="cat_ch" name="1">
   <div class="cat_ch" name="2">
   <div class="cat_ch" name="3">
   <div class="cat_ch" name="5">
   <div class="clear"> </div>
</div>

I want to loop though div.cat_ch How?

This one fails:

    $("div").each(function () {
       alert("FW");
       alert($(this).attr("name").val());
    });
