Stax解析XML的簡單一實例，stax解析xml

關鍵字解釋：

Stax:Streaming API for XML（用於讀寫XML的流介面）

xml檔案代碼：

<?xml version="1.0"?>  <service>      <item>          <task>test</task>          <strategy>repeat</strategy>      </item>      <item>          <task>WebpageRespTask</task>          <strategy>repeat</strategy>      </item>  </service>  

Java代碼：Junit4 testcase:TestStax
