How to display the xml parsing data in the UItextfield in iphone - iphone

Question

I am able to parse the xml data and able to display it in the console, but not able to display that data in the UITextField or in UILabel.
I tried to assign to textfield in the viewDidLoad method also.
The following is my code,
NSMutableString *currentNodeContent;
NSXMLParser *parser;
ViewController *currentProfile;
bool isStatus;
ViewController *xmlParser;
-(id)loadXMLByURL:(NSString *)urlString
{
_profile = [[NSMutableArray alloc] init];
NSURL *url = [NSURL URLWithString:urlString];
NSData *data = [[NSData alloc] initWithContentsOfURL:url];
parser = [[NSXMLParser alloc] initWithData:data];
parser.delegate = self;
[parser parse];
return self;
}
-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
currentNodeContent = (NSMutableString *) [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
}
-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
if([elementName isEqualToString:#"profileinfo"])
{
currentProfile = [ViewController alloc];
isStatus = YES;
}
if([elementName isEqualToString:#"first_name"])
{
currentProfile = [ViewController alloc];
isStatus = YES;
}
}
-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
if([elementName isEqualToString:#"first_name"])
{
currentProfile.firstName = currentNodeContent;
NSLog(#"%#",currentProfile.firstName);
first_Name.text = currentNodeContent;//UITextField
first_name.text = currentNodeContent;//Label
}
if([elementName isEqualToString:#"last_name"])
{
currentProfile.lastName = currentNodeContent;
NSLog(#"%#",currentProfile.lastName);
last_Name.text = currentProfile.lastName;
}
if([elementName isEqualToString:#"profileinfo"])
{
[self.profile addObject:currentProfile];
currentProfile = nil;
currentNodeContent = nil;
}
}
- (void)viewDidLoad
{
[super viewDidLoad];
xmlParser = [[ViewController alloc] loadXMLByURL:#"http://www.mxxxxx.net/xxx/xxxxx.aspx?type=proifileinfo&loginid=xxx#gmail.com"];
}

Answer 1

Instead of assigning the values directly to the 'UITextField' or 'UILabel', have the values stored in a string. And when the parsing action completed, assign the string value to the 'UITextField' or 'UILabel'; Probably you should do that in '-viewWillAppear' method :-)

Answer 2

Create a IBOutlet UILabel *label; in the interface, connect it in Interface Builder, and then you can set the text of it by label.text = #"Anything";

Answer 3

I have also the same problem while parsing XML parser.
currentNodeContent = (NSMutableString *) [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
}
You are using the above line to trim spaces and tabs. But sometimes It does not work.
So, I implement the following code. The code may be useful to you.
NSString *sname = [currentNodeContent stringByReplacingOccurrencesOfString:#"\n" withString:#""];
NSString *actualString = [sname stringByReplacingOccurrencesOfString:#"\t" withString:#""];
Then pass the actualString to whatever you required.
