IOS XMLParsing HTML标签进入描述字段

Question

我正在XMLparsing上，我成功获得了标题和其他描述，但是当我得到描述时，我也在描述字段中得到了html等，就像这样。如何从我的描述中删除它。在这里，我附上了我的xml解析方法。

我试图添加图像很多次，但是不知道我无法添加图像，所以我在这里添加了链接。

这里是XML链接，我也从中获得HTML标记。

在github MWFeedParser上有一个非常不错的项目。请检查此项目，它有一些方法

- (NSString *)stringByStrippingTags;
- (NSString *)stringWithNewLinesAsBRs;
- (NSString *)stringByRemovingNewLinesAndWhitespace;
- (NSString *)stringByDecodingHTMLEntities;
- (NSString *)stringByEncodingHTMLEntities; 

而且您可以像这样在您的项目中使用该方法

NSString *summary = [[[myHtmlStringToDecode stringByStrippingTags] stringByRemovingNewLinesAndWhitespace] stringByDecodingHTMLEntities];
