IOS NSXMLParser没有从元素中获取所有文本？

Question

我正在使用NSXMLParser来解析XML文件，它解析了一些元素的长描述，但是在某些元素上它只是跳过大部分文本并且只从末尾抓取一些文本。

        <thedescription>Woodfield Country Club, located in the heart of Boca Raton, is a wonderful private gated community. A championship golf course and tranquil lakes separate the quaint sub communities.  Once past the gate, Woodfield’s private back streets are lined with lush tropical landscaping. In the center of the country club’s beautiful grounds lies its exceptional clubhouse. This is where friends and neighbors get together to enjoy one of the 5 individual restaurants, Cascades Spa and Fitness Center, inviting swimming pool, or Youth Activities Center. Woodfield Country Club has an activity for everyone. </thedescription>

在这个XML中，它获得前两个社区的完整thedescription标签，但不是伍德菲尔德乡村俱乐部？即使我将该社区移动到XML文件的中间或开头。

我的解析器代码：

-(id) loadXMLByURL:(NSString *)urlString
{
    _communities            = [[NSMutableArray alloc] init];
    NSURL *url      = [NSURL URLWithString:urlString];
    NSData  *data   = [[NSData alloc] initWithContentsOfURL:url];
    parser          = [[NSXMLParser alloc] initWithData:data];
    parser.delegate = self;
    [parser parse];
    return self;
}

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

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

- (void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
    if ([elementname isEqualToString:@"community"])
    {
        currentCommunity = [Community alloc];

    }
    }

- (void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
            if ([elementname isEqualToString:@"name"])
        {
            NSString *trimmed = [currentNodeContent stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];

            currentCommunity.name = trimmed;
            currentNodeContent = nil;
        }
    if ([elementname isEqualToString:@"primaryImageURL"])
    {
        NSString *trimmed = [currentNodeContent stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];

        currentCommunity.imageURL = trimmed;
        NSLog(@"%@ ", trimmed);

        currentNodeContent = nil;
    }

        if ([elementname isEqualToString:@"thedescription"])
        {
            NSString *trimmed = [currentNodeContent stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];

            currentCommunity.commDescription = trimmed;
            currentNodeContent = nil;

    }
    if ([elementname isEqualToString:@"community"])
    {
        [self.communities addObject:currentCommunity];

        currentCommunity = nil;
        currentNodeContent = nil;
    }
}

我不知道为什么它适用于某些社区描述而不适用于其他社区描述？任何帮助将不胜感激。
