jQuery Method for Traversing Custom Attributes in Tags

In development, we sometimes add attributes to HTML tags, how to traverse and process them?

<ul>
<li name="li1" sortid="nav_1">aaaaaaa</li>
<li name="li1" sortid="nav_2">bbbbbbb</li>
<li name="li1" sortid="nav_3">cccccccc</li>
<li name="li1" sortid="nav_4">ddddddd</li>
<li name="li1" sortid="nav_5">eeeeeee</li>
<li name="li1" sortid="nav_6">fffffffffffffffff</li>
<li name="li1" sortid="nav_7">gggggggg</li>
<li name="li1" sortid="nav_8">hhhhhhhh</li>
<li name="li1" sortid="nav_9">iiiiiiiiiiiiiiiiiii</li>
</ul>
//Traverse by sortid
$("li[sortid^='nav_']").each(function(i){
      var sortid=$(this).attr("sortid");
});
//Traverse by name
$("[name=li1']).each(function(a,b){
       var sortid= $(b).attr("sortid");
});
//If a certain sortid is known to take an object
$("[sortid='nav_1']).attr("html");
$("[sortid='nav_1']).attr("name");

Other:

//Search for the text object with the name clssId
$("input[name='clssId']").val();
//Search for IDs with certain regularities, such as searching for dd tags with id=single_xxx
$("dd[id^=single_]").each(function(){
      var id = $(this).attr("id");
      alert(id.substring(7));
});
