NSXMLParser解析xml格式的数据 用法如下：
首先，NSXMLParser必须继续NSXMLParserDelegate协议
@interface XMLHelper : NSObject <NSXMLParserDelegate>
首先设置XML数据，并初始化NSXMLParser

- (void)viewDidLoad { NSMutableString *Strxml=[NSMutableString stringWithString:@"<Body><xml1>11111111</xml1><xml2><xml3>3333333333</xml3></xml2></Body>"]; NSData *data=[NSData dataWithBytes:[Strxml UTF8String] length:[Strxml length]];
[parser setShouldProcessNamespaces:NO]; [parser setShouldReportNamespacePrefixes:NO]; [parser setShouldResolveExternalEntities:NO];
[parser parse]; [super viewDidLoad]; } |
//遍例xml的节点
|
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict { NSLog(@"Name:%@",elementName); } |
//当xml节点有值时，则进入此句
|
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { NSLog(@"Value:%@",string); } |
//当遇到结束标记时，进入此句
|
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
