Display number of XML elements in a textfield - ios

Question

I have an XML file somewhere on the web with a couple of profiles inside it and I want the number of profiles to be displayed in a textfield.
I have a textfield called: numberOfProfiles.. so what should I do in viewDidLoad?
numberOfProfiles.Text = ???
The XML file is being parsed like this:
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:#"firstname"])
{
currentProfile = [ViewController alloc];
isStatus = YES;
}
if([elementName isEqualToString:#"lastname"])
{
currentProfile = [ViewController alloc];
isStatus = YES;
}
if([elementName isEqualToString:#"email"])
{
currentProfile = [ViewController alloc];
isStatus = YES;
}
if([elementName isEqualToString:#"address"])
{
currentProfile = [ViewController alloc];
isStatus = YES;
}
}
-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
if([elementName isEqualToString:#"firstname"])
{
currentProfile->firstName = currentNodeContent;
NSLog(#"%#",currentProfile->firstName);
[profile addObject:currentProfile];
}
if([elementName isEqualToString:#"lastname"])
{
currentProfile->lastName = currentNodeContent;
NSLog(#"%#",currentProfile->lastName);
[profile addObject:currentProfile];
}
if([elementName isEqualToString:#"email"])
{
currentProfile->eMail = currentNodeContent;
NSLog(#"%#",currentProfile->eMail);
[profile addObject:currentProfile];
}
if([elementName isEqualToString:#"address"])
{
currentProfile->address = currentNodeContent;
NSLog(#"%#",currentProfile->address);
[profile addObject:currentProfile];
}
if([elementName isEqualToString:#"profiles"])
{
[self->profile addObject:currentProfile];
currentProfile = nil;
currentNodeContent = nil;
setText:currentProfile->lastName;
}
}
- (void)viewDidLoad
{
[super viewDidLoad];
xmlParser = [[ViewController alloc] loadXMLByURL:#"http://dierenpensionlindehof.nl/profiles.xml"];
}
Thanks in advance!

Answer 1

for just count of element you can have an instance variable like of int type numberOfProfilesCount and you can increment this in
-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
numberOfProfilesCount++;
}
and in
- (void)parserDidEndDocument:(NSXMLParser *)parser {
numberOfProfiles.Text = [NSString stringWithFormate:#"%d", numberOfProfilesCount];
}
to show your element count

Answer 2

Assuming profile is a global variable, use [profile count] to get the number of profiles.
The try: [numberOfProfiles setText:[[profile count] stringValue]
