Parsed xml file but the array is showing null - ios

Question

I have parsed the xml file.
The console is showing the parsed elements correctly but the array is showing null.
- (ParserClass *) initXMLParser
{
//[super init];
appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
return self;
}
- (void)parser: (NSXMLParser *)parser didStartElement:(NSString *) elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName
attributes:(NSDictionary *)attributeDict {
if([elementName isEqualToString:#"note"]) {
//Initialize the array.
appDelegate.testArray = [[NSMutableArray alloc] init];
}
else if([elementName isEqualToString:#"to"]) {
aTest = [[Test alloc] init];
}
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;
if([elementName isEqualToString:#"note"]) {
[appDelegate.testArray addObject:aTest];
//[aBook release];
aTest = nil;
}
else
[aTest setValue:currentElementValue forKey:elementName];
//[currentElementValue release];
currentElementValue = nil;
}
#end

Try to change your initialization to:
- (ParserClass *) initXMLParser {
self=[super init];
if(self !=nil){
appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
// init array of user objects here
appDelegate.testArray = [[NSMutableArray alloc] init];
}
return self;
}
And,if your xml is:
<books>
<note>
<something>cccc</something>
</note>
<note>
<something>cccc</something>
</note>
</books>
So you need change:
-(void)parser: (NSXMLParser *)parser didStartElement:(NSString *) elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName
attributes:(NSDictionary *)attributeDict {
if([elementName isEqualToString:#"note"]) {
aTest = [[Test alloc] init];
//if you have attributes, you can extract them here:
// user.att = [[attributeDict objectForKey:#"<att name>"] ...];
}
NSLog(#"Processing Element: %#", elementName);
}
And to get your array you must do something like this:
//Data store your xml
NSXMLParser *nsXmlParser = [[NSXMLParser alloc] initWithData:Data];
ParserClass *parser = [[ParserClass alloc] initXMLParser];
//delegate your parser
[nsXmlParser setDelegate:parser];
//it's doing parsing
BOOL success = [nsXmlParser parse];
if (success)
{
NSMutableArray *someArray = [parser appDelegate.testArray ];
NSLog(#"%#",someArray );
} else
{
NSLog(#"Error parsing document!");
}
try it , it working for me...
