XSLT 3.0 - 如何正确使用 apply-templates 和 copy-of？

问题描述 投票：0回答：1

我对 xslt 3.0 相当陌生，并且有一个需要使用它的问题。我非常接近，但我的输出正在打印我不想要的数据的纯文本副本。

我基本上必须将 T3 块与 T4 块合并，仅适用于具有员工 ID 且还必须获取标题数据的工作人员。

XSLT：

所需输出：请注意，由于 Matt Carp 没有员工 ID，因此我不希望他出现在输出中。然而我上面的代码似乎在一个字符串中打印出了他的所有 T4 块，如下所示：4xyz333MATTHEWCARP

声明一下就足够了 

<xsl:mode name="in-memory" on-no-match="shallow-skip"/>
。
