I want to parse this xml file and display it in viewdidload.i have completed the coding.but cant display in image view and textview seperately.Please help me.

Answer 1

This is how I parse an XML file very similar to yours. This basically converts the XML into a plist file.

#pragma mark - Delegate Received

-(void)parsingComplete:(XMLDataSource*)theParser {
    NSArray *categoryArray = [theParser getCategories];
    [categoryArray writeToFile:PLIST atomically:YES];
}
- (void)receivedItems:(NSArray *)theItems {
    NSMutableArray *dataItems = [[NSMutableArray alloc] init];
    [dataItems addObjectsFromArray:[NSArray arrayWithContentsOfFile:PLIST]];

    NSDictionary * dataItem = [dataItems objectAtIndex:categoryIndex];
    data_ =  [dataItem objectForKey:@"images"];
}

#pragma mark - Parsing Delegates

- (void)parse:(NSData *)data withDelegate:(id)sender onComplete:(SEL)callback 
{
    parentDelegate = sender;
    onCompleteCallback = callback;
    loading = YES;

    NSXMLParser *parser = [[NSXMLParser alloc] initWithData:data];
    [parser setDelegate:self];
    [parser setShouldProcessNamespaces:NO];
    [parser setShouldReportNamespacePrefixes:NO];
    [parser setShouldResolveExternalEntities:NO];
    [parser parse];
}
- (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError {
    parsed = NO;
    loading = NO;
}
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict 
{
    NSString *element = [elementName stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
    currentElement = element;
    if ([[currentElement lowercaseString] isEqual:@"image"]) {
        inImage = YES;
        itemsDictionary = [[NSMutableDictionary alloc] init];
        [itemsDictionary addEntriesFromDictionary:attributeDict];
    }

    if ([[currentElement lowercaseString] isEqual:@"category"]) {
        inCategory = YES;
        categoryDictionary = [[NSMutableDictionary alloc] init];

    }
}

    if ([[element lowercaseString] isEqual:@"image"]) {

    }

    if ([[element lowercaseString] isEqual:@"category"]) {
        inCategory = NO;

    /*  skip over blank elements.  */
    if (stringValue == nil || [stringValue isEqual:@""]) {
        return;
    }

    if (element != nil && [element length] > 0) {
        if (inImage) {
            if ([itemsDictionary objectForKey:element] != nil) {
                [itemsDictionary setObject:[NSString stringWithFormat:@"%@%@", [itemsDictionary objectForKey:element], stringValue]

                [root setObject:stringValue forKey:element];
            }

    }
}
