iOS--XML解析

Sax解析：

- (void)startParser{    //解析    NSString * Path = [[NSBundle mainBundle]pathForResource:@"Student" ofType:@"xml"];    //根据文件路径将文件转化为二进制    NSData *data = [NSData dataWithContentsOfFile:Path];        NSXMLParser *xml = [[NSXMLParser alloc]initWithData:data];    xml.delegate = self;    //开始解析    [xml parse];}

2. 调用NSXMLParser的initWithData:方法，并设置代理delegate

@protocol SaxXmliParserDelegate <NSObject>- (void)saxXmlvalueToFirstWith:(NSArray *)array;@end//定义协议@property (nonatomic,assign)id<SaxXmliParserDelegate>delegate;

<p style="margin-top: 0px; margin-bottom: 0px; font-size: 14px; font-family: 'Heiti SC Light'; color: rgb(0, 132, 0);"><pre name="code" class="objc">//遵循协议- (void)saxXmlvalueToFirstWith:(NSArray *)array{    [_tableArray addObjectsFromArray:array];}

3.代码实现(三种必须实现方法)

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{    if ([elementName isEqualToString:KstuArray]) {        NSMutableDictionary * stuDic = [NSMutableDictionary dictionary];        //把另外字典放在一个新的字典中        [stuDic addEntriesFromDictionary:attributeDict];                NSMutableArray *stuArr = [NSMutableArray array];        [stuDic setObject:stuArr forKey:@"array"];        [_sarray addObject:stuDic];    }    if ([elementName isEqualToString:Kstu]) {        Model * model = [[Model alloc]init];        NSMutableDictionary * lastDic = [_sarray lastObject];//放在字典中        NSMutableArray *lastArr = [lastDic objectForKey:@"array"];//放在数组中        [lastArr addObject:model];        //[model release];    }}

//处理标签包含内容字符 （报告元素的所有或部分内容）- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{      self.currentValue = string;}

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{    if ([elementName isEqualToString:kname]) {        NSMutableDictionary * dic = [_sarray lastObject];        NSMutableArray *arr = [dic objectForKey:@"array"];                Model *model = [arr lastObject];        model.name = _currentValue;    }    if ([elementName isEqualToString:kage]) {        NSMutableDictionary * dicAge = [_sarray lastObject];        NSMutableArray *arrAge = [dicAge objectForKey:@"array"];        Model *model = [arrAge lastObject];        model.age = _currentValue;    }    if ([elementName isEqualToString:ktel]) {        NSMutableDictionary * dicTel = [_sarray lastObject];        NSMutableArray *arTel = [dicTel objectForKey:@"array"];        Model *model = [arTel lastObject];        model.tel = _currentValue;    }    if ([elementName isEqualToString:Kroot]) {        NSLog(@"kroot ===== %@",_sarray);    }        [self.delegate saxXmlvalueToFirstWith:_sarray];}
