用于IOS的XMLparsing器SDK

我需要能够为我正在处理的项目parsingXML。

我怎样才能从一个网页parsingXML到iPhone然后阅读它的内容？

Answer 1

按照这个， 如何使用ASIHTTPRequest parsingObjective C中的XML并处理所有这些方法

-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict -(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName -(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
