xpath2.0的函數怎麼使用?该怎么处理

xpath2.0的函數怎麼使用?
我的xslt是1.0的,那麼xpath應該也是1.0的吧?
所以我想使用xpath2.0的函數max()的時候,是不是必須升級到xpath2.0?
但是我不知道怎麼升級,是不是只是改xslt的文件頭信息就好了?

Will MSXML support XSLT 2.0?

No. MSXML versions 4.0 and later fully implement and support XSL Transformations (XSLT) Version 1.0 (W3C Recommendation 16 November 1999). If your XML application requires a later version of XSLT, Microsoft strongly recommends moving to the newer System.Xml framework classes, because all future XML development efforts will be focused there.


Use XSLT 2.0 functions in Eclipse WTP Helios
