Re: iPhone XML Parse

Hi,

One example:

...

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName
attributes:(NSDictionary *)attributeDict {

if([elementName isEqualToString:@"Books"]) {
//Initialize the array.
appDelegate.books = [[NSMutableArray alloc] init];
}
else if([elementName isEqualToString:@"Book"]) {

//Initialize the book.
aBook = [[Book alloc] init];

//Extract the attribute here.
aBook.bookID = [[attributeDict objectForKey:@"id"] integerValue];

NSLog(@"Reading id value :%i", aBook.bookID);
}

NSLog(@"Processing Element: %@", elementName);
}


- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {

if(!currentElementValue)
currentElementValue = [[NSMutableString alloc] initWithString:string];
else
[currentElementValue appendString:string];

NSLog(@"Processing Value: %@", currentElementValue);

}

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {

if([elementName isEqualToString:@"Books"])
return;

//There is nothing to do if we encounter the Books element here.
//If we encounter the Book element howevere, we want to add the book object to the array
// and release the object.
if([elementName isEqualToString:@"Book"]) {
[appDelegate.books addObject:aBook];

[aBook release];
aBook = nil;
}
else
[aBook setValue:currentElementValue forKey:elementName];

[currentElementValue release];
currentElementValue = nil;
}


All of these, go into the .m, correct?

If I have an xml file with 3 companys, each with 6 factorys, and each factory with the attributs, how do I populate a table the companys, for example?
