无法使用XSLT 2.0从XML中删除重复值

我试过下面的解决办法

<xsl:for-each-group select="/esbMsg/rqData/customer" group-by="identityNumber">
         <xsl:sequence select="."/>
       </xsl:for-each-group>

但这对我不起作用。因为我的XML有名称空间。我删除了上面的名称空间，解决方案运行良好。由于我有需求，我需要名称空间来调用下一个服务

我正在努力消除重复的

源文档中的元素位于各种名称空间中，您在路径表达式中完全忽略了这些名称空间。您需要在路径表达式中使用前缀名称，并将名称空间前缀绑定到正确的名称空间。

我也使用了前缀，结果为空@Prabhatsigh

identityNumber

也在名称空间中。@michael.hor257k谢谢你的指针它对我有用
