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"]) 
开发者_Go百科{
    [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];
}

//[currentElementValue release];

currentElementValue = nil;
}

can Anyone tell me what mistake i done here. It giving an error: NSXMLParserErrorDomain error 41

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).

try dont giving spaces for the tag names, say, u gave <Question Title>test for mitesh</Question Title>

make it

<QuestionTitle>test for mitesh</QuestionTitle>

Other tags also, and try

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.
