我在分组一组节点时遇到了麻烦。
我发现了一篇与分组有关的文章，我测试了它，它适用于我有的小测试样式表
我现在需要在我的样式表中使用它，我只想选择具有特定值的节点集。
我想在样式表中做的是选择用户级别为2的所有用户，然后按志愿者区域对其进行分组。
一分钟发生的事情是它使用userlevel 2获得了适当数量的用户但不打印它们。它只是重复xml文件中的第一个用户。

<additional>Oxford Folk Festival is going into it's third year in 2006. As well as needing volunteers to steward for the event on the weekend itself, we would be delighted to hear from people willing to help in year round festival work such as stuffing envelopes for mailings, poster and leaflet distribution, and stewarding duties at festival pre-events.</additional>

您在for-each元素中正确使用了相对路径表达式，但是当您传递参数时，您错误地切换到绝对路径。所以而不是像。
<xsl:with-param name="myid" select="/folktask/member/user/@id" />
我想你想要的。
<xsl:with-param name="myid" select="../user/@id" />
当然，而不是所有那些命名模板和繁琐的call-template / with-param，你可以（并且应该在我的视图中）编写匹配模板并使用apply-templates。
