OC-Xml文件解析

本次解析使用的由Google提供的一个开源插件：GDataXmlNode对xml文件的解析。

导入GDataXmlNode文件和配置Xcode :http://blog.csdn.net/hmt20130412/article/details/24042499

题目：解析如下Xml文件，通过输入城市中文名，获取对应城市的首字母。例如：输入常德输出c

xml文件：

新建了一个类Xml解析类：ParseAlphAndCityName.h

 1 #import <Foundation/Foundation.h>
 2 
 3 @interface ParseAlphAndCityName : NSObject
 4 {
 5     NSMutableDictionary *_alphAndCityNameList;
 6 }
 7 
 8 @property (retain,nonatomic)NSMutableDictionary *alphAndCityNameList;
 9 
10 
11 - (id)init;
12 
13 
14 - (void)parseXml:(NSString *)xmlFilePath;
15 
16 
17 + (void)test:(NSString *)xmlFilePath;
18 
19 @end

ParseAlphAndCityName.m

最主要的是parseXml:(NSString *)xmlFilePath;方法。利用了主流的对xml的解析方法。

不多说：看代码，已经注释的很清楚了。
