iPhone-解析XML文件-请帮助！

我需要解析xml文件的帮助。我的问题是我不知道如何实现DiEndElement委托。
我想要的是，我将有两个单元，在那里展示旧约和新约，然后是圣经的书籍和章节。 如果我能在xml解析方面得到一些帮助，剩下的我就可以处理了

我将非常感谢您的帮助

谢谢和问候

我的xml文件如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<bible>
 <testament name="Old Testament">
  <book name="Genesis">
   <chapter id="Genesis 1"></chapter>
   <chapter id="Genesis 2"></chapter>
  </book>
  <book name="Exodus">
   <chapter id="Exodus 1"></chapter>
   <chapter id="Exodus 2"></chapter>
  </book>
 </testament>
 <testament name="New Testament">
  <book name="Matthew">
   <chapter id="Matthew 1"></chapter>
   <chapter id="Matthew 2"></chapter>
  </book>
  <book name="Revelation">
   <chapter id="Revelation 1"></chapter>
   <chapter id="Revelation 2"></chapter>
  </book>
 </testament>
</bible>

以下是调试器控制台的输出：

你已经在分析它了。在

didEndElement:

调用中，只需对元素执行任何操作。因为您的XML不包含任何包装字符串（您没有使用

foundCharacters:

），所以您所要做的就是相应地响应

didStartElement:

和

didEndElement:

。如果需要捕获属性或分配新的数据结构来容纳可能的子级，请在

didStartElement:

中执行。如果需要将对象保存到集合中或以某种方式完成特定元素的处理，请在

didEndElement:

中执行

这个问题实际上不是关于解析的，而是关于您想要为响应解析而执行的任何逻辑

编辑以下评论：

在解析过程中，我通常会执行以下操作来保存对象：在我的接口中，我声明了需要将对象保存到的集合，以及一个临时对象，在将其添加到集合之前，我使用该临时对象保存所需的任何数据，如下所示

@interface MyClass : NSObject <NSXMLParserDelegate>{
    NSMutableArray *collection_;
    SomeObject *tempObject_;
}
@end

---

然后对集合对象执行您将要执行的操作。确保你处理了内存问题，比如释放集合对象或者其他什么。我通常使用委托回调（我自己设计的）之类的方法将集合获取到模型，以便从逻辑上将解析与模型分离。

不要再次回滚我的编辑欢迎使用堆栈溢出。这个问题完全无法理解。请使用“101010”按钮格式化您的代码，并在点击post之前检查预览。如果你看不懂，那我们怎么看呢？很抱歉。我在想怎么做。谢谢你，理查德！嗨Kevboh，我感谢你的帮助。事实上，我正在尝试“将对象保存到集合中”。这正是我遇到问题的地方。任何帮助都将不胜感激。Kevboh，非常感谢！这对我帮助很大！我可以从这里开始。嗨，凯夫布，非常感谢！很高兴知道像你这样的人会花时间伸出援助之手！
