iphonexml反序列化程序

我是编程新手，这是我的第一个项目，所以我对xml解析等没有太多概念。 我需要解析一个xml文档，比如

<TLMS><TLMSResponse status="SUCCESS">
 <books>
  <book>
   <name>abc</name>
   <author>DEF</author>
   <publisher>HIJ</publisher>
  </book>

  <book>
   <name>xyz</name>
   <author>rus</author>
   <publisher>tuv</publisher>
  </book>
 </books>
</TLMSResponse></TLMS>

abc
DEF
你好
xyz
罗斯
tuv

我已经尝试了很多，但还没有找到任何好的反序列化程序可以解析这个xml并生成“Book”类的对象。 非常感谢您的帮助

---

谢谢大家

下面是一个实现该协议的示例类

它将解析此xml：

<TLMS><TLMSResponse status="SUCCESS">
<books>
<book>
<name>abc</name>
<author>DEF</author>
<publisher>HIJ</publisher>
</book>

<book>
<name>xyz</name>
<author>rus</author>
<publisher>tuv</publisher>
</book>
</books>
</TLMSResponse></TLMS>
