Java：利用XML生成Word文档
Word 2003后提供了一种xml的文档格式。可以利用这一点方便的生成doc文档
Word 2007更完全使用xml与数据压缩包的方式存储，使得用类似的方法处理附件也变为可能。

概述
实现步骤如下：
- 定义Word文档样式，存为xml文档。
- 定义数据xml格式，生成样本数据。
- 修改word文档样式xml文件，制作xsl模板文件。
- 编程实现：数据->xml数据->模板转换->doc文档
创建模板
打开Word文档，另存为：Word 2003 xml格式。
使用xsl编辑器 （如 Stylus Studio）或手工编辑，创建XSL模板 。
相关XSL问题可以参考 http://www.w3schools.com/xsl/
利用dom4j处理相关xml操作
下面是一些基础实现方法
