How to find namespace XML avoid other name in jQuery

I have problem with parsing XML on jQuery. I have XML file like this

<field name="scheduleItems">
   <value>
     <field name="programID">364</field>
     <field name="programTime">05:00</field>
     <field name="programTimeEnd">05:30</field>
   <value>
</field>

And this is my code when use ajax for parsing

$.ajax({
    type: "GET",
    url: xmlFeed,
    dataType: "xml",
    success: function(xml) {
        $(xml).find("field[name*='scheduleItems']").each(function(i, obj){
             $(xml).find("value").each(function(i, obj){
                 var programTime = $(this).children("field[name*='programTime']").text();
                 var programTimeEnd = $(this).children("field[name*='programTimeEnd']").text();
              });
        });   
    },
    error: function() {
        console.log("has error!");
    }
 });  

When I print result of programTime. programTimeEnd will append like this >> "programTime":"05:0005:30"

Can I resolve it. Thanks all.
