NSXMLParser values not being retained.
- by user574947
This is similar to my previous question. I didn't get an answer, maybe by changing the question I might get an answer.
Here is my parsing code:
-(void) parser:(NSXMLParser *) parser didStartElement:(NSString *) elementName
namespaceURI:(NSString *) namespaceURI
qualifiedName:(NSString *) qName
attributes:(NSDictionary *) attributeDict
{
if ([elementName isEqualToString:kimgurl]
|| [elementName isEqualToString:kone_x]
|| [elementName isEqualToString:kone_y]
|| [elementName isEqualToString:kone_radius]
|| [elementName isEqualToString:ktwo_x]
|| [elementName isEqualToString:ktwo_y]
|| [elementName isEqualToString:ktwo_radius])
{
elementFound = YES;
theItems = [[Items alloc] init];
}
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName
{
if([elementName isEqualToString:kimgurl])
{
theItems.imageURL = self.currentValue;
[self.currentValue setString:@""];
}
else if([elementName isEqualToString:kone_x])
{
theItems.iOne_X = self.currentValue;
[self.currentValue setString:@""];
}
else if([elementName isEqualToString:kone_y])
{
theItems.iOne_Y = self.currentValue;
[self.currentValue setString:@""];
}
else if([elementName isEqualToString:kone_radius])
{
theItems.iOne_Radius = self.currentValue;
[self.currentValue setString:@""];
}
else if([elementName isEqualToString:ktwo_x])
{
theItems.iTwo_X = self.currentValue;
[self.currentValue setString:@""];
}
else if([elementName isEqualToString:ktwo_y])
{
theItems.iTwo_Y = self.currentValue;
[self.currentValue setString:@""];
}
else if([elementName isEqualToString:ktwo_radius])
{
theItems.iTwo_Radius = self.currentValue;
[self.currentValue setString:@""];
}
}
-(void) parserDidEndDocument:(NSXMLParser *)parser
{
NSLog(@"enddocument: %@", theItems.imageURL);
}
-(void)parser:(NSXMLParser *) parser foundCharacters:(NSString *)string
{
if (elementFound == YES) {
if(!currentValue)
{
currentValue = [NSMutableString string];
}
[currentValue appendString: string];
}
}
When I get to parserDidEndDocument. The theItems class is empty.
Here is Items.h
#import <Foundation/Foundation.h>
@interface Items : NSObject {
@private
//parsed data
NSString *imageURL;
NSString *iOne_X;
NSString *iOne_Y;
NSString *iOne_Radius;
NSString *iTwo_X;
NSString *iTwo_Y;
NSString *iTwo_Radius;
}
@property (nonatomic, retain) NSString *imageURL;
@property (nonatomic, retain) NSString *iOne_X;
@property (nonatomic, retain) NSString *iOne_Y;
@property (nonatomic, retain) NSString *iOne_Radius;
@property (nonatomic, retain) NSString *iTwo_X;
@property (nonatomic, retain) NSString *iTwo_Y;
@property (nonatomic, retain) NSString *iTwo_Radius;
@end
here is Items.m
#import "Items.h"
@implementation Items
@synthesize imageURL;
@synthesize iOne_X;
@synthesize iOne_Y;
@synthesize iOne_Radius;
@synthesize iTwo_X;
@synthesize iTwo_Y;
@synthesize iTwo_Radius;
-(void)dealloc
{
[imageURL release];
[iOne_X release];
[iOne_Y release];
[iOne_Radius release];
[iTwo_X release];
[iTwo_Y release];
[iTwo_Radius release];
[super dealloc];
}
@end
here is my RootViewController.h
#import <UIKit/UIKit.h>
@class Items;
@interface RootViewController : UIViewController <NSXMLParserDelegate> {
NSMutableData *downloadData;
NSURLConnection *connection;
BOOL elementFound;
NSMutableString *currentValue;
NSMutableDictionary *pictures;
//---xml parsing---
NSXMLParser *xmlParser;
Items *theItems;
NSMutableArray *aItems;
}
@property (nonatomic, retain) Items *theItems;
@property (nonatomic, retain) NSMutableArray *aItems;
@property (nonatomic, retain) NSMutableString *currentValue;
@property (nonatomic, retain) NSMutableData *downloadData;
@property (nonatomic, retain) NSURLConnection *connection;
@end
