How to read a xml file in iOS - xml-parsing

Question

I want to read a xml file within my iOS. Im reading it like this
NSURL *url = [[NSURL alloc] initWithString:urlString] ;
purchasedBookXMLParser = [[NSXMLParser alloc] initWithContentsOfURL:url];
PurchasedBookXMLParser *bookParser = [[PurchasedBookXMLParser alloc] initPurchasedBookXMLParser];
[purchasedBookXMLParser setDelegate:bookParser];
BOOL success = [purchasedBookXMLParser parse];
But im getting success NO always. When I give the same url in browser I can see the xml data. What is the reason for this. How can I solve this. Please help me.
Thanks

Answer 1

Did u implement parser delegate method ??
In my project what i am doing is as below
NSURL *url = [NSURL URLWithString:#"https://api.sportsdatallc.org/nascar-p3/sc/2015/races/schedule.xml?api_key=wstdt33unpyk7sgpmjj5qver"];
parser = [[NSXMLParser alloc] initWithContentsOfURL:url];
[parser setDelegate:self];
[parser setShouldResolveExternalEntities:NO];
[parser parse];
After that parser delegate methods call i.e. as below
If u want data between "race" tag then [element isEqualToString:#"race"]
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
NSString *element;
element = elementName;
if ([element isEqualToString:#"race"])
{
item2=[[NSMutableDictionary alloc] init];
[item2 setObject:attributeDict forKey:#"race"];
}
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
}
- (void)parserDidEndDocument:(NSXMLParser *)parser
{
[self.tableview reloadData];
}
