在开发中经常会用到各种kv类型的配置 文件，像这样的
<?xml version="1.0" encoding="utf-8" ?> <source> <item id="101" value="1125"/> <item id="102" value="413"/> <item id="103" value="181"/> <item id="104" value="1642"/> <item id="105" value="926"/> <item id="106" value="1088"/> <item id="107" value="1243"/> </source>
那么我们可以用一个辅助类来很好的解决哦

其中“EXMLDataSource”就是配置文件名的枚举了。
这个辅助类提供增改查功能，使用方便。只需要这么调用就可以了
XMLSourceHelp.SH.ConvertIdToName("101", XMLSourceHelp.EXMLDataSource.Lightweight);
