解析本地／网络上的xml文件

 

http://blog.csdn.net/sjzsp/article/details/6314740

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

2、解析网络xml文件

 

#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receivedData

xmlRead = [[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];

}
