NSXMLParser Issue - iphone

Question

I have an xml file I am parsing.
NSURL *url = [NSURL URLWithString:#"url.xml"];
NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60];
self.downloadData = [[NSMutableData alloc] initWithLength:0];
self.connection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];
I have all the connections working and I thought I had the parsing working but I am having issues and do not know what I am doing wrong.
my didStartElement:
-(void) parser:(NSXMLParser *) parser didStartElement:(NSString *) elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *) qName attributes:(NSDictionary *) attributeDict {
if ([elementName isEqualToString:kimgurl])
{
elementFound = YES;
}
}
foundCharacter:
-(void)parser:(NSXMLParser *) parser foundCharacters:(NSString *)string {
if (elementFound == YES) {
if(!currentValue)
{
currentValue = [[NSMutableString alloc] init];
}
[currentValue appendString: string];
}
}
then didEndElement:
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
if (elementFound) {
if ([elementName isEqualToString:kimgurl]) {
NSLog(#"imgurl: %#", currentValue);
imageItems.imageURL = currentValue;
NSLog(#"elname: %#", elementName);
NSLog(#"img: %#", kimgurl);
[currentValue setString:#""];
NSLog(#"imageitem: %#", imageItems.imageURL);
}
}
}
I have the NSLogs there because imageItems.imageURL is null. This is a class file that is like this.
ImageItems.h
#interface ImageItems : NSObject {
//parsed data
NSString *imageURL;
}
#property (nonatomic, retain) NSString *imageURL;
#end
ImageItems.m
#import "ImageItems.h"
#implementation ImageItems
#synthesize imageURL;
-(void)dealloc
{
[imageURL release];
[super dealloc];
}
#end
As you can tell by my code I am new to objective-c.
currentValue has the value Im looking for. Why is imageItems null? What am I missing?

I don't see the assignment of "imageItems" anywhere in your code. You probably need to assign it to an instance of ImageItems at some point. Perhaps with self.imageItems = [[[ImageItems alloc] init] autorelease] or imageItems = [[ImageItems alloc] init];?
