根据我的要求，我必须对两个不同的X路径（如下面的

）进行排序 
accountList/previousAccount/account/accNo
accountList/account/accNo

我使用了后代，这对我的要求不起作用。请帮我解决这个问题。

实际输出

02 JOHN RICHARD
07 PETE KEVIN
1 
20 JOHN HEWIT
24 WOOD HILARI

期待输出

   01 REMOVED   NASH
   02           JOHN RICHARD
   07           PETE KEVIN
   08 REMOVED   ADOGA
   09 HOLD      LUCAS
   20           JOHN HEWIT
   24 HOLD       DONALD

答案 0 :(得分：0)

  

在我的要求中，我得对它们进行排序，这些都来自两个   不同的X路径如下

accountList/previousAccount/account/accNo
accountList/account/accNo

也许你可以在没有两个不同XPath的地方做到这一点。如果你减少了上面的XPath，删除previousAccount就会发现它们基本相同。您只需要搜索accountList ...

的后代 
accountList//account/accNo

如果您使用xsl:for-each或xsl:apply-templates执行此操作，您的排序会变得更加轻松。任何其他过滤，例如firstName != 'xxx'都可以添加到谓词中。

我认为这是你最初尝试的内容，但却因xsl:for-each-group而崩溃了。

这是一个例子（also seen here）。我完全猜测输出的实际格式;特别是田野的填充物。我可能过度复杂了，但它至少应该是一个开始。

输出（这对我来说并不明显为什么＆＃34; WOOD HILARI＆＃34;应该被排除在外）
