Can't parse XML with NSXMLParser - ios

Question

I got an iOS app. All data stores in xml files.
<?xml version="1.0" encoding="utf-8"?>
<objects>
<object
name="Скульптура Р. Исмагилова «Пермяк – соленые уши»"
xcoord="58.00998487478568"
ycoord="56.239829063415527"
type=""
description=""
external_name="gl1" />
</objects>
So, i want to parse this XML file to NSMutableArray
I do it with NSXMLParser deleagate class. This is class's code:
#implementation XMLParser
#synthesize aPLace;
- (XMLParser *) initXMLParser {
[super init];
appDelegate = (XMLAppDelegate *)[[UIApplication sharedApplication] delegate];
return self;
}
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName
attributes:(NSDictionary *)attributeDict {
NSLog(#"parsing");
if([elementName isEqualToString:#"objects"]) {
//Initialize the array.
appDelegate.books = [[NSMutableArray alloc] init];
}
else if([elementName isEqualToString:#"object"]) {
//Initialize the book.
aPLace = [[Place alloc] init];
//Extract the attribute here.
aPLace.name = [[attributeDict objectForKey:#"name"] string];
NSLog(#"Reading name :%#", aPLace.name);
}
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
if([elementName isEqualToString:#"objects"])
return;
if([elementName isEqualToString:#"object"]) {
[appDelegate.greenLine addObject:aPLace];
}
}
#end
You can see that there is NSLog(#"parsing"); in didStartElement function. But output is empty.
So, i implement parsing in AppDelegateClass's function applicationDidFinishLaunching
- (void)applicationDidFinishLaunching:(UIApplication *)application {
NSURL *url = [[NSURL alloc] initWithString:#"greenline_ru.xml"];
NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithContentsOfURL:url];
//Initialize the delegate.
XMLParser *parser = [[XMLParser alloc] initXMLParser];
//Set delegate
[xmlParser setDelegate:parser];
//Start parsing the XML file.
BOOL success = [xmlParser parse];
if(success)
NSLog(#"No Errors");
else
NSLog(#"Error Error Error!!!");
// Configure and show the window
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
}
and every time output is Error Error Error!!! why? What's the problem?

Answer 1

NSURL *url = [[NSURL alloc] initWithString:#"greenline_ru.xml"];
I think this is your problem. If you have file you should use something like
NSString *path = [[NSBundle mainBundle] pathForResource:#"greenline_ru"
ofType:#"xml"];
[[NSXMLParser alloc] initWithData:[NSData dataWithContentsOfFile:path]]

Use TBXML, this is quite easy to use...
