通过tbxml解析xml后删除特殊字符

Question

我在解析XML内容并在ui中显示时遇到问题。 XML有就是这个样子

但是之后我分析它（直通TBXML）我得到的字符串作为

我曾尝试已经提到的解决方案的数量元素的含量清理特殊字符，例如 HTML character decoding in Objective-C/Cocoa Touch 甚至修改的方法，包括“A”，双空间似乎没有任何工作..

我不能使用Github上NSString category for HTML因为该代码似乎不兼容ARC，当我尝试在我的项目中使用它时，出现各种各样的错误。

有人可以帮助我在正确的方向..拉我的头发在这一段时间:-(我想，必须有一个简单的方法在一个通用的方法来做到这一点。
