       method: "GET",

       },  
       success: function (data) {  
         var userProfileDetails = data;  
         var propertyKey="XYZ";  
         var PropertyValuePair = $.grep(userProfileDetails.d.UserProfileProperties.results, function (v) {  
           return v.Key === propertyKey;  
         });  
         var propertyValue = PropertyValuePair[0].Value  
       },  
       error: function (jqxr, errorCode, errorThrown) {  
         alert(jqxr.responseText);
