Copy XML file from Server to iphone?

I want to copy the xml file from server to save it to locally, because if I will send request to server again and again, it will take time, so I want to copy the xml to local resources whenever app starts, then parse the local xml,

how can I do it?

First of all you need to download the file:

    NSURL *url = [NSURL URLWithString:FILEURL];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [NSURLConnection connectionWithRequest:request delegate:self];

then add in the h file:

NSMutableData *receivedData;

and in the m file:

    -(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
    {
        if (receivedData)
        {
            [receivedData appendData:data];
        }
        else 
        {
            receivedData = [[NSMutableData alloc] initWithData:data];
        }
    }

    -(void) connectionDidFinishLoading:(NSURLConnection *)connection
    {
        //saving your data in the local

        NSString *docDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
        NSString *fullName = [NSString stringWithFormat:@"xmlfile.xml"];

        NSString *fullFilePath = [NSString stringWithFormat:@"%@/%@",docDir,fullName];
        [receivedData writeToFile:fullFilePath atomically:YES];

    }

edit: get the file from local-

NSString *docDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
        NSString *fullName = [NSString stringWithFormat:@"xmlfile.xml"];

        NSString *fullFilePath = [NSString stringWithFormat:@"%@/%@",docDir,fullName];
NSData *myData = [NSData dataWithContentsOfFile:filePath];

now you can take the NSData when parse it,there are a lot of examples in the site.
