Answer 1

請在NSObject的一個文件，然後使用方法在解析元素

- (void)parserDidStartDocument:(NSXMLParser *)parser 
    { 
    } 

- (void) parser: (NSXMLParser *) parser parseErrorOccurred: (NSError *) parseError { 
} 

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

- (void) parser: (NSXMLParser *) parser didEndElement: (NSString *) elementName namespaceURI: (NSString *) namespaceURI 
    qualifiedName: (NSString *) qName{ 


if ([elementName isEqualToString:@"webResponseData"]) 
{ 
    [communication addObject:[currentElement stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; 
} 
currentElement = nil; 
} 

- (void) parser: (NSXMLParser *) parser foundCharacters: (NSString *) string { 

if(!currentElement) 
    currentElement = [[NSMutableString alloc] initWithString:string]; 
else 
    [currentElement appendString:string]; 
} 

然後在視圖 - 控制進口分析器文件connectiondidfinishloading和使文件 例子的目的： -

NSString *responseStringCommunication=[[NSString alloc]initWithData:MutableData encoding:NSUTF8StringEncoding]; 

Parser *parser=[[Parser alloc]init]; 

NSMutableArray *array=[parser parse:responseStringCommunication];
