我的Parser类看起来像：

#import <Foundation/Foundation.h>

@interface Parser : NSXMLParser

@property (nonatomic,strong) NSString *rowElementName; // this is the element name that identifies a new row of data in the XML
@property (nonatomic,strong) NSArray *attributeNames;  // this is the array of attributes we might want to retrieve for that element name
@property (nonatomic,strong) NSArray *elementNames;    // this is the list of sub element names for which we're retrieving values

@property (nonatomic,strong) NSMutableArray *items;    // after parsing,this is the array of parsed items

@end

和

#import "Parser.h"

@interface Parser () <NSXMLParserDelegate>

@property (nonatomic,strong) NSMutableDictionary *item;     // while parsing,this is the item currently being parsed
@property (nonatomic,strong) NSMutableString *elementValue; // this is the element within that item being parsed

@end

@implementation Parser

- (id)initWithContentsOfURL:(NSURL *)url
{
    self = [super initWithContentsOfURL:url];

    if (self)
    {
        self.delegate = self;
    }

    return self;
}

- (id)initWithData:(NSData *)data
{
    self = [super initWithData:data];

    if (self)
    {
        self.delegate = self;
    }

    return self;
}

- (id)initWithStream:(NSInputStream *)stream
{
    self = [super initWithStream:stream];

    if (self)
    {
        self.delegate = self;
    }

    return self;
}

#pragma mark - NSXMLParserDelegate methods

我的目标是获取< description>中的所有信息.标记并显示它像Google-Maps一样

不完全但是相似.

但首先我需要知道如何与Parser一起工作

最好的问候CTS
