我的当前脚本出现了问题，我正在处理xbmc的键盘事件。当我按下键盘的输入按钮时，代码将通过重新获取XML标签中的相同值来继续触发，它会一遍又一遍地重复执行它并且它将保持存储相同的值在数据库中，当来自XML标签的名称为'display-name'的值很少时。
以下是代码：

这是xml日志：http://xbmclogs.com/show.php?id=143587
这是数据库：http://testbox.elementfx.com/source.db
这是xml文件：http://ontv.dk/xmltv/c81e728d9d4c2f636f067f89cc14862c
我只想在数据库中写入值，而不是在从XML标记中获取值时反复重新获取相同的值。
当我将它们存储在数据库中而不像循环那样继续运行时，你知道如何能够一次又一次地重新获取相同的值吗？
