parse XML to NSArray of NSDictionary - error - why? - nsarray

Question

I have a problem parsing a XML to NSArray of NSDictionary. I don't know why, but instead of the array gets 2 objects (in this case), it take 2 objects with equal data... Why?
Here's the code:
#interface RLparseXMLToArrayOfDictionarys : NSObject <NSXMLParserDelegate> {
NSMutableArray *arrayWithResult;
NSMutableDictionary *tempDict;
NSMutableString *currentString;
NSString *groupKey;
}
#property (nonatomic, strong) NSString *groupKey;
#property (nonatomic, retain) NSMutableArray *arrayWithResult;
#property (nonatomic, retain) NSMutableDictionary *tempDict;
-(NSArray *)parseXMLWithStringToArray:(NSString *)stringWithXML withGroupKey:(NSString *)groupKeyToIgnore;
#end
#implementation RLparseXMLToArrayOfDictionarys
#synthesize groupKey;
#synthesize arrayWithResult;
#synthesize tempDict;
- (id)init
{
self = [super init];
if (self) {
}
return self;
}
-(NSArray *)parseXMLWithStringToArray:(NSString *)stringWithXML withGroupKey:(NSString *)groupKeyToIgnore{
NSData *currentStringData = [stringWithXML dataUsingEncoding:NSUTF8StringEncoding];
NSXMLParser *parser = [[NSXMLParser alloc] initWithData:currentStringData];
[parser setDelegate:self];
// Set Parser Options
[parser setShouldProcessNamespaces:NO];
[parser setShouldReportNamespacePrefixes:NO];
[parser setShouldResolveExternalEntities:NO];
//key to ignore
self.groupKey = groupKeyToIgnore;
if (!arrayWithResult) {
arrayWithResult = [[NSMutableArray alloc] init];
}
if (!tempDict) {
tempDict = [[NSMutableDictionary alloc] init];
}
[parser parse];
NSLog(#"return: %#", arrayWithResult);
return arrayWithResult;
}

}
[currentString appendString:string];
}

{
NSString *currentStringNoWhiteSpace = [currentString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
if ([elementName isEqualToString:groupKey]){
[arrayWithResult addObject:tempDict];
// [tempDict removeObjectsForKeys:[tempDict allKeys]];
}
else if (currentStringNoWhiteSpace != nil)
[tempDict setValue:currentStringNoWhiteSpace forKey:elementName];
currentStringNoWhiteSpace = nil;
currentString = nil;
}
- (void)parserDidEndDocument:(NSXMLParser *)parser {
}
#end

Done!
Replace [tempDict removeObjectsForKeys:[tempDict allKeys]];
with tempDict = [[NSMutableDictionary alloc] init];
