这被称为数据和显示式分离，这非常好，当我们想要改变风，主要换一个XSL就行了，并不需要重新添加一份数据。但是有的时候也是有特例的，比如我们就有这个奇怪的需求---将XML/XSL写到一个文件。百度后，没有结果；忽然灵机一动，不是有一个很热门的问答网站

这被称为数据和显示格式分离，这非常好，当我们想要改变风格，主要换一个xsl就行了，并不需要重新添加一份数据。

但是有的时候也是有特例的，比如我们就有这个奇怪的需求---将XML/XSL写到一个文件。百度后，没有结果；忽然灵机一动，不是有一个很热门的问答网站（stackoverflow）吗！

我就去搜索了一下，果然有个仁兄给出了一个很NICE的答案。我先列出来，后面有时间写个自己修改后的版本。
