从jquery中的ajax调用中调用Javascript函数

Question

  $.ajax({
         type: "GET",
         url: "tmpdata.xml",
         dataType: "xml"
    }).done(function(xml){   
 // alert("Hello Yagya");
        file  = $(xml).find("segment[id="+metric+"][name="+segment+"]").text();
        alert("Calling tmp file function");
        tmp(file);
   }); 

//Consider metric and segment names are alraedy assigned

In above code I am trying to call javascript function after fetching filename from xml file, But It seems that due to asynchronous call, tmp function is not called and also unable to access file name outside ajax function, please help me to come out of this problem.

Try this

$.ajax({
     type: "GET",
     url: "tmpdata.xml",
     dataType: "xml",
     success:function(xml){   
    // alert("Hello Yagya");
    file  = $(xml).find("segment[id="+metric+"][name="+segment+"]").text();
    alert("Calling tmp file function");
    tmp(file);
   }
});
