我被困在试图计算总和（数量）*价格在xslt 2.0

首先，我的任务是按提供者名称对元素进行分组，总计数量为@ItemNumber，并计算total = quantity * Price。我无法做出这个计算，我得到错误。这是我迄今为止所做的。任何帮助将不胜感激。我被困在试图计算总和（数量）*价格在xslt 2.0

这是我的XSLT

那么，您获得发布的代码到底是哪个错误？对于哪些代码行？你为什么试图在XSLT 2.0中使用'ex：node-set'？ –

如果您使用XSLT 2.0，那么你可以简单地使用：

<xsl:value-of select="sum(current-group()/(Quantity * Price))" />

两个分组级别，并且：

<xsl:value-of select="sum(Item/(Quantity * Price))" />

为总计。
