什麼時候XML解析在iPhone應用程序中完成？

Question

我正在使用普通的XML解析器並將XML的值存儲在字典中。

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName 
    namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName 
{ 
    if([elementName isEqualToString:@"CountryId"]){ 
     currentTweet.content = currentNodeContent; 
     [data setObject:currentTweet.content forKey:@"CountryId"]; 
     //NSLog(@"currentNode is %@",currentNodeContent); 
    } 
    if([elementName isEqualToString:@"CountryName"]){ 
     currentTweet.createdAt = currentNodeContent; 
     [data setObject:currentTweet.createdAt forKey:@"CountryName"]; 
     //NSLog(@"currentNode is countnry Name %@",currentNodeContent); 
    } 

    /*if([elementName isEqualToString:@"Country"]){ 
     [tweets addObject:currentTweet]; 

     tweet *current  = [tweets objectAtIndex:0]; 

     NSLog(@"value of current is %@",current.content); 
     NSLog(@"value of Country tweet is %@",current.createdAt); 
     [currentTweet release]; 
     currentTweet = nil; 
     [currentNodeContent release]; 
     currentNodeContent = nil; 
    }*/ 
} 
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string 
{ 
    currentNodeContent = [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; 
} 

我想了解一些方法，它告訴我，當XML數據是完全讀取並存儲在數組中。我使用這些方法通過Web代理方法，因爲我來自視野肥皂讀取數據並加載整理我的XML傳遞給XML解析器是這樣的：

-(void) connectionDidFinishLoading:(NSURLConnection *) connection { 
    NSLog(@"DONE. Received Bytes: %d", [webData length]); 
    NSLog(@"recived data %@",webData); 
    NSString *theXML = [[NSString alloc] 
       initWithBytes: [webData mutableBytes] 
       length:[webData length] 
       encoding:NSUTF8StringEncoding]; 
    //---shows the XML--- 
    NSLog(@"%@",theXML); 
    [theXML release];  


    if(xmlParser) 
    { 
     [xmlParser release]; 
    } 

    xmlParser = [[NSXMLParser alloc] initWithData: webData]; 
    //[xmlParser setDelegate: self]; 
    [xmlParser setShouldResolveExternalEntities: YES]; 
    [xmlParser parse]; 

    [connection release]; 
    [webData release]; 
}
