The data has been read and stored in data beforehand.

Create a class that inherits from NSObject and names it userInfo

@ property (nonatomic,copy) NSString * uID;@property (nonatomic,copy) NSString * name;@property (nonatomic,copy) NSString * password;@property (nonatomic,copy) NSString * nickname;@property (nonatomic,copy) NSString * description

Create another class, which is also inherited from NSObject and named userParser, to read the xml file.

UserParser.h

# import # import "user.h" @ interface userParser: array of NSObject// storage information @ property (nonatomic,retain) NSMutableArray * array;// instance @ property (nonatomic,retain) user * people;// create string save information @ property (nonatomic,copy) NSMutableString * buffer;// read xml file-(void) parserWithString: (NSString *) string;@end

Userparser.m

# import "userParser.h" @ implementation userParser- (void) parserWithString: (NSString *) string {/ / use system XML parsing method NSXMLParser * parser= [[NSXMLParser alloc] initWithData: [string dataUsingEncoding:NSUTF8StringEncoding]]; / / set proxy parser.delegate=self; / / start parsing [parser parse];} # pragma mark-NSXMLParserDelegate---// start parsing-(void) parserDidStartDocument: (NSXMLParser *) parser {NSLog (@ "it begin") } / / end of parsing-(void) parserDidEndDocument: (NSXMLParser *) parser {NSLog (@ "it is over"); for (int iTuno; I
