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];
[categoryDictionary addEntriesFromDictionary:attributeDict];
}
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName
{
NSString *element = [elementName stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
if ([[element lowercaseString] isEqual:#"image"]) {
inImage = NO;
[items addObject:[itemsDictionary copy]];
}
if ([[element lowercaseString] isEqual:#"category"]) {
inCategory = NO;
[categoryDictionary setObject:[items copy] forKey:#"images"];
[items removeAllObjects];
[categories addObject:[categoryDictionary copy]];
}
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
NSString *stringValue = [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
NSString *element = [currentElement stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
/* 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]
forKey:element];
} else {
[itemsDictionary setObject:stringValue forKey:element];
}
} else if ((!inImage) && (inCategory)) {
if ([categoryDictionary objectForKey:element] != nil) {
[categoryDictionary setObject:[NSString stringWithFormat:#"%#%#", [categoryDictionary objectForKey:element], stringValue]
forKey:element];
} else {
[categoryDictionary setObject:stringValue forKey:element];
}
} else {
if ([root objectForKey:element] != nil) {
[root setObject:stringValue forKey:element];
}
}
}
}
- (void)parserDidStartDocument:(NSXMLParser *)parser {
NSError * err;
if(![[NSFileManager defaultManager] fileExistsAtPath:PLIST]) {
[[NSFileManager defaultManager] removeItemAtPath:PLIST error:&err];
}
}
- (void)parserDidEndDocument:(NSXMLParser *)parser

loading = NO;
if ([parentDelegate respondsToSelector:onCompleteCallback]) {

SHOW_ALERT(#"parserDidEndDocument:", #"receivedItems: not responding!", nil, #"Okay", nil)
