这是我得到的错误，有人可以给我一个它应该是什么样的例子。我知道这一定很愚蠢，但我正在画一个空白。

 Element must have a match attribute
 xsl:key

【问题讨论】：

好问题，+1。请参阅我的回答，解释问题以及如何解决问题。

标签： xml xslt

【解决方案1】：

<xsl:key name="movie"/>

这是非法/无效的。

<xsl:key> 指令必须具有match 和use 属性。

类似：

<xsl:key name="kMovieByName" match="movie" use='.'/>

另外，您的代码根本没有使用key() 函数，因此您只需从中删除<xsl:key>，错误就会消失。
