iPhone/iPad 开发: 解析本地／网络上的xml文件(实例建附件)
1、解析本地xml文件
//找到本地test.xml文件 NSString*path = [[NSBundlemainBundle] pathForResource:@"test"ofType:@"xml"]; NSFileHandle*file = [NSFileHandlefileHandleForReadingAtPath:path]; NSData*data = [file readDataToEndOfFile];//得到xml文件//开始解析NSXMLParser* xmlRead = [[NSXMLParseralloc] initWithData:data];//初始化NSXMLParser对象[data release];[xmlRead setDelegate:self];//设置NSXMLParser对象的解析方法代理[xmlRead parse];//调用代理解析NSXMLParser对象，看解析是否成功
#define URIString @"http://192.168.247.76:8899/hisyo_cn/test.xml"//首先链接网络文件NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:URIString] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:15];NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];if (theConnection) { //得到文件数据receivedData=[[NSMutableData data] retain];} else{NSLog(@"error");}- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{ [receivedData setLength:0];}- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{ [receivedData appendData:data];}- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{ [connection release]; [receivedData release]; NSLog(@"Error"); //超过设定好的链接时间显示链接失败 [theContent setText:@"Connection defeat"];}- (void)connectionDidFinishLoading:(NSURLConnection *)connection{NSString *content = [[NSString alloc] initWithData: receivedData encoding: NSUTF8StringEncoding];NSLog(@"content: %@",content);[theContent setText:content]; //开始解析获取的receivedDataxmlRead = [[NSXMLParser alloc] initWithData:receivedData];[xmlRead setDelegate:self];//设置NSXMLParser对象的解析方法代理[xmlRead parse];//调用代理解析NSXMLParser对象，看解析是否成//NSString *content = [[NSString alloc] initWithData: receivedData encoding: NSJapaneseEUCStringEncoding];[connection release];[receivedData release];}
