需要使用XSLT 1.0从XML输出中基于2个条件删除重复元素

Question

我在这里已经查看了几个答案，我无法将头缠在键上并删除重复的元素。在我的用例中，我有一个随机排列的附件列表。对于我的输出，如果文件名和文件大小都不相同，则仅需要输出附件

这是我的输入内容：

 <Attachments NR="1">

在我的输出中，我需要删除具有相同FileName和FileSizeKB的元素。我知道使用键和分组可能是实现此目的的方法，但到目前为止我还没有运气。

到目前为止，这是我的XSLT模板中的内容：

<xsl:key name="kAttachmentByFileName" match="//Attachments" use="FileName"/>

 <xsl:for-each select="//Attachments">
    <xsl:copy-of select="//Attachments[generate-id()=generate-id(key('kAttachmentByFileName', .)[1])]"/>
   <vbo:Attachments>
       <vbo:Attachment>
          <cmn:Name xmlns:cmn="xxxxxx">
              <xsl:value-of select="FileName" />
          </cmn:Name>
          <cmn:BinaryObject xmlns:cmn="xxxx">
              <xsl:value-of select="DataBase64" />
          </cmn:BinaryObject>
       </vbo:Attachment>
    </vbo:Attachments>
</xsl:for-each>
