parsing xml response from web service

i have a web service in my IOS application which will return a xml with returned data

this is my .m file:

 #import "ViewController.h"

 @interface ViewController (){
SYSoapTool *soaptool;
 }

 @end

 @implementation ViewController

 - (void)viewDidLoad
 {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.

soaptool = [[SYSoapTool alloc]init];
[soaptool setDelegate:self];


NSMutableArray *tag=[[NSMutableArray alloc] initWithObjects:@"oid", nil];
NSMutableArray *varse=[[NSMutableArray alloc] initWithObjects:@"10", nil];
[soaptool callSoapServiceWithParameters__functionName:@"GetContainer" tags:tag vars:varse wsdlURL:@"http://ift.tt/VbVm3W"];



 }



 -(void) retriveFromSYSoapTool:(NSMutableArray *)_data{
NSLog(@"data: %@",_data);



 }

 - (void)didReceiveMemoryWarning
 {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
 }

 @end

what i want is to fetch data from the array (_data) to print it in the screen of the application not in the debugger for example label 1 will contains the first data retrived and so on

how to do that ?
