NSXMLParser

IPhone之NSXMLParser的使用

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=[NSMutableStringstringWithString:@"<Body><xml1>
11111111</xml1><xml2><xml3>3333333333</xml3></xml2></Body>"];

NSData *data=[NSData dataWithBytes:[Strxml UTF8String]length:[Strxml length]];

NSXMLParser *parser = [[NSXMLParser alloc] initWithData:data];//设置XML数据

[parser setShouldProcessNamespaces:NO];

[parser setShouldReportNamespacePrefixes:NO];

[parser setShouldResolveExternalEntities:NO];

[parser setDelegate:self];

[parser parse];

[super viewDidLoad];

}

//遍例xml的节点

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString*)elementName
namespaceURI:(NSString *)namespaceURIqualifiedName:(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 *)namespaceURIqualifiedName:(NSString *)qName

{

}
