大家可以看到，我已经在

上应用了

键。多个
中存在多个

现在，我想分别处理每个
，然后对其中存在的所有
应用分组。在此代码中发生的是，所有
中的所有
一次都分组在一起
第1行显示了此转换的一个结果。对于单个
，它应该显示特定
（比如ADT）的
总数。但是，它考虑了整个XML中的所有

所以我应该得到“1”个ADT，我得到的是“2”
如何处理它？
听起来好像您想使用一个由多个元素组成的复合键。在本例中，您是通过a:T\u ShoppingFile和a:LocalPaxType进行挖掘的，因此您可能需要这样的内容
<xsl:key 
   name="item" 
   match="b:T_AirBookingItem" 
   use="concat(generate-id(..) , '|', a:LocalPaxType)" />



然后，对于每个a:T\u ShoppingFile要获得唯一的a:LocalPaxType记录，只需执行以下操作
<xsl:apply-templates 
  select="b:T_AirBookingItem[generate-id() 
    = generate-id(key('item', concat(generate-id(..) , '|', a:LocalPaxType))[1])]" />



这是完整的XSLT
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:res="http://schemas.datacontract.org/2004/07/Trevoo.WS.IO.Shopping" xmlns:a="http://schemas.datacontract.org/2004/07/Trevoo.WS.Entities.Shopping" xmlns:b="http://schemas.datacontract.org/2004/07/Trevoo.WS.Entities.Air" xmlns:c="http://schemas.microsoft.com/2003/10/Serialization/Arrays" xmlns:bb="http://schemas.datacontract.org/2004/07/Trevoo.WS.Entities.Shopping.Views" exclude-result-prefixes="res a b c bb">
   <xsl:output method="xml" indent="yes"/>

   <xsl:key name="item" match="b:T_AirBookingItem" use="concat(generate-id(..) , '|', a:LocalPaxType)"/>

   <xsl:template match="/">
      <xsl:apply-templates select="//a:T_ShoppingFile"/>
   </xsl:template>

   <xsl:template match="a:T_ShoppingFile">
      <file number="{position()}">
         <xsl:apply-templates select="b:T_AirBookingItem[generate-id() = generate-id(key('item', concat(generate-id(..) , '|', a:LocalPaxType))[1])]"/>
      </file>
   </xsl:template>

   <xsl:template match="b:T_AirBookingItem">
      <result>
         <xsl:value-of select="concat(a:LocalPaxType, ' * ', count(key('item', concat(generate-id(..) , '|', a:LocalPaxType))), '&#13;')"/>
      </result>
   </xsl:template>
</xsl:stylesheet>



应用于XML时，将输出以下内容
<file number="1">
   <result>ADT * 1</result>
   <result>CHD * 1</result>
   <result>INF * 1</result>
</file>
<file number="2">
   <result>ADT * 1</result>
</file>


ADT*1
冠心病*1
INF*1
ADT*1

显然，这显示了所有a:T_ShoppingFile和a:LocalPaxType的结果。如果您想限制为一个特定的a:LocalPaxType，您可以这样做（尽管您可能希望参数化该值，而不是硬编码ADT
   <xsl:template match="a:T_ShoppingFile">
      <file number="{position()}">
         <xsl:value-of select="count(key('item', concat(generate-id() , '|', 'ADT')))" />
      </file>
   </xsl:template>


这真的很有帮助。精确地解决了我的问题。谢谢：）使用“复合键”的想法很棒！！确保键的两个部分中都不会出现连接这两个部分的分隔符（在本例中为条）。
