基于XML-XSL的订单存储与拆分. xsl:function与xsl:result-document XSLT2.0

XSLT2.0新增了许多XSLT1.0不支持的功能.

xsl:function与xsl:result-document属于其新增功能.

xsl:function主要是通过将自定义方法关联到相对应的名称空间,然后通过提供参数以及返回对应结果.

xsl:result-document主要应用是通过在template或者是for-each中对于节点信息进行输出到独立文件.(常见于订单数据的存储以及提取)

以下的代码模拟将一个存储在orders.xml中的订单数据拆分出来.主要用到了以上所说的这两个标签.

存储orders.xml
