1、解析本地xml文件

Java代码  
//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

Java代码  
#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];
}
