I don't know if it's intended, but what currently happening is:

When you find a predefined element (any you've named in an if-statement), you create an empty array (temp) and add your object in it. The XML parser then proceeds to the next element. In the next element, you empty your array and add that object.

So, in the end, only the LAST element found is added: xml_api_reply

Solution? Try to create an array in something like viewDidLoad and do not create an empty array in every element, but add everything to an existing one (so: without creating an empty one and overwriting your existing array with it)

To make thing clear, using this code should do the trick:

-(void)parser:(NSXMLParser *)parser didStartElement:(NSString*) elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString*)qualifiedName attributes:(NSDictionary*)attributeDict
{

    if ([elementName isEqualToString:@"xml_api_reply"])
    {
        mWeather = [[TWeatherElement alloc]init];
    }

    if([elementName isEqualToString:@"current_date_time"])
    {
        [mParserArray addObject:[attributeDict valueForKey:@"data"]];
    }

    if([elementName isEqualToString:@"condition"])
    {
        [mParserArray addObject:[attributeDict valueForKey:@"data"]];
    }

    if([elementName isEqualToString:@"humidity"])
    {
        [mParserArray addObject:[attributeDict valueForKey:@"data"]];
    }

    if([elementName isEqualToString:@"icon"])
    {
        [mParserArray addObject:[attributeDict valueForKey:@"data"]];
    }

    if([elementName isEqualToString:@"wind_condition"])
    {
        [mParserArray addObject:[attributeDict valueForKey:@"data"]];
    }

    if([elementName isEqualToString:@"low"])
    {
        [mParserArray addObject:[attributeDict valueForKey:@"data"]];
    }

    if([elementName isEqualToString:@"high"])
    {
        [mParserArray addObject:[attributeDict valueForKey:@"data"]];
    }

The problem is in this part of the code

if([elementName isEqualToString:@"wind_condition"])
    {
        NSMutableArray *temp=[[NSMutableArray alloc]init];
        self.mParserArray=temp;
        [temp release];


        [mParserArray addObject:[attributeDict valueForKey:@"data"]];

    }

You need to create the array once and assign mParserArray(which should have retain property ) to it. Later you should keep adding objects to your mParserArray like

mParserArray addObject:[attributeDict valueForKey:@"data"]];

Do not create array and override them in every if statement.

Try the given below code:

- (void)viewDidLoad {


fcdayofweek = [[NSMutableArray alloc]init];
fclow = [[NSMutableArray alloc]init];
fchigh = [[NSMutableArray alloc]init];
fccondition = [[NSMutableArray alloc]init];
fcicon = [[NSMutableArray alloc]init];
NSString *url = [[NSString alloc]initWithString:@"http://www.google.com/ig/api?weather=,,,50500000,30500000"];
NSLog(@"%@",url);


NSURL *xmlURL = [[NSURL alloc]initWithString:url];
[url release];
//[[NSURLCache sharedURLCache] setMemoryCapacity:0];
//[[NSURLCache sharedURLCache] setDiskCapacity:0];
NSXMLParser *parser = [[NSXMLParser alloc]initWithContentsOfURL:xmlURL];
NSLog(@"Start parsing");
[xmlURL release];
[parser setDelegate:self];
[parser parse];
[parser release];
parser = nil;

[super viewDidLoad];
}

In your parser delgate method use the code:

       /*------- prasing delegate methods ---------------*/
- (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError {

[UIApplication sharedApplication].networkActivityIndicatorVisible=NO;
UIAlertView * errorAlert = [[UIAlertView alloc] initWithTitle:@"Sorry!" message:@"Data is temporarily unavailable . Please try again in a few minutes." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[errorAlert show];
[errorAlert release];

}
