Iphone NSXMLParser不能正确处理“；

我在iPhone应用程序中解析xml时遇到一些问题。下面是我想用标准的

NSXMLParser

parser解析的xml代码的一部分

我试图获取标题并保存它，但我的解析器工作错误。解析器只获取“符号后的文本

我能做什么？谁能告诉我parse发生了什么？非常感谢

您能给我们展示一下您的

-parser:foundCharacters:

的实现吗？如何存储

字符串

我还曾经在XML文件中使用过带有特殊字符的

NSXMLParser

，它工作起来没有问题。

下面是

-parser:foundCharacters:

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
    //in case of unusable tags
    if (currentArticle == nil) {
        return;
    }
    // Get Title.   
    if ([currentElement isEqualToString:@"title"]) {
        [self.currentArticle setTheTitle:string];
    // Get Description.
    } else if ([currentElement isEqualToString:@"description"]) {
        string = [string stringByReplacingOccurrencesOfString: @"\n" withString: @"" ];
        [self.currentArticle setTheSummary:string];

    } else if ([currentElement isEqualToString:@"link"]) {
        [self.currentArticle setTheMainLink:string];

    } else if([currentElement isEqualToString:@"guid"]){
        [self.currentArticle setTheImageLink:string];

    } else if ([currentElement isEqualToString:@"pubDate"]) {
        [self.currentArticle setThePubDate:string];

    } else if([currentElement isEqualToString:@"author"]){
        [self.currentArticle  setTheAuthor:string];
    }
}

我注意到解析器第一次从开始到结束有两次获得标题，第二次从结束到结束。就像在我的提要中一样，有两个title标签

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

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
    //in case of unusable tags
    if (currentArticle == nil) {
        return;
    }
    // Get Title.   
    if ([currentElement isEqualToString:@"title"]) {
        [self.currentArticle setTheTitle:string];
    // Get Description.
    } else if ([currentElement isEqualToString:@"description"]) {
        string = [string stringByReplacingOccurrencesOfString: @"\n" withString: @"" ];
        [self.currentArticle setTheSummary:string];

    } else if ([currentElement isEqualToString:@"link"]) {
        [self.currentArticle setTheMainLink:string];

    } else if([currentElement isEqualToString:@"guid"]){
        [self.currentArticle setTheImageLink:string];

    } else if ([currentElement isEqualToString:@"pubDate"]) {
        [self.currentArticle setThePubDate:string];

    } else if([currentElement isEqualToString:@"author"]){
        [self.currentArticle  setTheAuthor:string];
    }
}
