《自拍教程65》Python Testlink用例导出工具xml2excel

准备阶段

操作Xml的模块，我建议首选ElementTree, 本次用官方自动的ElementTree即可

操作Excel的模块，一直首选openpyxl

Python面向对象类形式

由于本案例涉及的代码有些许难度，且相对较长，

直接以面向对象类的形式来进行建模及程序设计。

建模：先设想有这么一个空白的世界，这个世界需要哪些类型的事物（名词）。

我们需要两个类，一个是ExcelParser类用于解析Excel获取Excel数据，

一个是XMLWriter类，用于将以上获取的Excel数据写入Xml文件里去。
