NSXMLParser解析简例
本篇以以下类型的XML为例解析：
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="e0">密码错误</string>
<string name="e1">手机号不存在</string>
<string name="e2">未找到该城市</string>
<string name="e3">参数异常</string>
<string name="e4">鱼种库为空</string>
<string name="e6">文件为空</string>
<string name="e7">参数异常或为空</string>
<string name="e8">发布失败</string>
<string name="e10">token异常,请重新登录</string>
<string name="e11">钓点不存在</string>
<string name="e12">钓点id未找到</string>
<string name="e13">钓点id错误</string>
<string name="e14">收藏失败</string>
<string name="e15">已收藏</string>
<string name="e16">经纬度参数错误</string>
<string name="e18">城市不能为空</string>
<string name="e17">无更多钓点</string>
<string name="e19">插入失败</string>
<string name="e20">手机号码或验证码不正确</string>
<string name="e21">参数类型错误</string>
<string name="e22">数据写入错误</string>
</resources>
