Please Tell Me How to parse This xml File

I did Following Code for parsing

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


if([elementName isEqualToString:@"Question"]) 
{
    [QuesIdArray addObject: [attributeDict objectForKey:@"id"]];
}
   else if([elementName isEqualToString:@"Question Title"]) 
{

}
else if([elementName isEqualToString:@"Question Description"]) 
{

}
else if([elementName isEqualToString:@"Creator Name"]) 
{

}
else if([elementName isEqualToString:@"Creation Date"]) 
{

}
else if([elementName isEqualToString:@"Respondent Names"]) 
{

}
else if([elementName isEqualToString:@"Anonymous Answers"]) 
{

}

else if([elementName isEqualToString:@"Expiry Date"]) 
{

}

  }

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

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


NSLog(@"Processing Value: %@", currentElementValue);


  }



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

if(currentElementValue) 
    currentElementValue = [currentElementValue stringByTrimmingCharactersInSet: [NSCharacterSet whitespaceAndNewlineCharacterSet]];

if([elementName isEqualToString:@"Error"]) 
{

    //appDelegate.ErrorString = [ [ NSString alloc ] initWithString: currentElementValue ] ;
}

else if([elementName isEqualToString:@"Question Title"]) 
{

    [QuesTitleArray addObject:currentElementValue];
}
else if([elementName isEqualToString:@"Question Description"]) 
{

    [QuesTextArray addObject:currentElementValue];
}
else if([elementName isEqualToString:@"Creator Name"]) 
{
    [QuesCreatorArray addObject:currentElementValue];
}
else if([elementName isEqualToString:@"Creation Date"]) 
{
    [QuesCreationDateArray addObject:currentElementValue];
}
else if([elementName isEqualToString:@"Respondent Names"]) 
{
    [ResNamesArray addObject:currentElementValue];
}
else if([elementName isEqualToString:@"Anonymous Answers"]) 
{
    [QuesAnswerArray addObject:currentElementValue];
}

else if([elementName isEqualToString:@"Expiry Date"]) 
{

    [QuesExpiryDateArray addObject:currentElementValue];

NSXMLParserErrorDomain error 41 means that an attribute doesn't have a value. Because you are not naming elements correctly, you ultimately get an attribute without a value.

From NSXMLParser reference - 41 error code value is NSXMLParserAttributeHasNoValueError

The problem is that your xml is malformed as xml tag names cannot contain spaces. For example

<Question Title>...

Here tag name is 'Question' and 'Title' is interpreted as attribute name, which has no value. You should correct your xml to fix that (i.e. remove spaces in tag names).
