  • Xml+Xslt导出Excel实例

    　　最近研究了一下基于xml+Xslt的统计报表导出Excel功能，原有的设计是用JS实现，优点是实现起来比较简单，缺点同样很明显，对导出复杂的表格无能为力，而且需要客户端安装Excel，另一种办法是在服务器端实现，调用office的DLL直接操作Excel，可控范围较广，但是遇到大数据量的统计报表则响应较慢，这对于客户来说是无法忍受的。于是，就有了基于xml+xslt的解决方案。由于Excel可另存为后缀名为.xml的数据格式，这就为这种解决方案提供了实现的可能性。
    　　实现原理：由于统计报表是基于xml+xslt实现，从数据库取出的数据已保存在xml中，我们只需要将这xml暂存下来，然后用导出Excel所用的xslt文件转换即可。
    　　实现过程：
          用于导出Excel所用的DepositExcel.xslt

    　　这里有个小窍门，一般我们设计统计报表，都是先制作完成DepositStatistic.xslt，与xml结合后的报表呈现无误后，即可在页面上复制报表，粘贴到Excel，再在Excel里另存为xml 电子表格格式，再打开这个文件，去掉冗余的代码，即可得到DepositExcel.xslt.
