我对 XSLT 比较陌生，但想要执行我认为是元素之间相对简单的匹配以获得另一个元素。

这是 XML 的一个片段。版本 = 1.0，输出为文本（将 xml 转换为文本）。

我要做的是将节点//Accounts/Account/Id 与//InvestmentHoldingBalances/HoldingBalance/AccountId 匹配，当匹配时，获取属于该帐户ID 的相应//Owners/Owner/Id。当我进行匹配时，我得到的结果是所有行的第一个 //Owners/Owner/Id，而不是单个匹配的行。这是我的 xslt；

<?xml version="1.0" encoding="ISO-8859-1"?>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="text" indent="yes" />

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

<!--  Create Header Record -->
<xsl:template match="xxxxxx">
<!-- Some other xslt here to extract header info -->
 <xsl:apply-templates select="InvestmentHoldingBalances/HoldingBalance" />  
</xsl:template> 

<!-- Create HoldingBalance Records -->
<xsl:template match="HoldingBalance">
<xsl:value-of select="AccountId" />
<xsl:text>","</xsl:text>
<xsl:value-of select="InvestmentCode" />
<xsl:text>","</xsl:text>
<xsl:value-of select="Exchange" />
<xsl:text>","</xsl:text>
  <xsl:if test="../../Accounts/Account/Id=AccountId">
  <xsl:value-of select="../../Accounts/Account/Owners/Owner/Id" />
 </xsl:if>   
<xsl:text>"</xsl:text>
<xsl:text disable-output-escaping="yes">&#10;</xsl:text> 
</xsl:template>

</xsl:stylesheet>

输出的是每一行的相同Owner Id（即'273228M'最后一列），而不是根据Account Id匹配的Owner Id；

273228MD399","TEST123","FND","273228M"
273228MD301","0114AU","FND","273228M"
273228MD301","0016AU","FND","273228M"
273228MD301","0277AU","FND","273228M"
273228MD999","TD0155","FND","273228M"

我追求的结果是这样的；

273228MD399","TEST123","FND","2732299"
273228MD301","0114AU","FND","273228M"
273228MD301","0016AU","FND","273228M"
273228MD301","0277AU","FND","273228M"
273228MD999","TD0155","FND","27322YY"

感谢您的任何建议。

基本问题在于

<xsl:value-of select="../../Accounts/Account/Owners/Owner/Id"/>

select 表达式选择整个文档中的所有所有者 ID，而不考虑帐户 ID，当您要求value-of一组多个节点时，规范将结果定义为文档中集合中第一个节点的值命令。

您需要以某种方式将集合限制为仅匹配的帐户，最简单的方法是

<xsl:value-of select="../../Accounts/Account[Id = current()/AccountId]/Owners/Owner/Id"/>

但是在样式表的顶层定义一个键可能更有效（直接放在xsl:output元素之后）

<xsl:key name="accountById" match="Account" use="Id"/>

value-of然后您可以在使用中提取正确的帐户

<xsl:value-of select="key('accountById', AccountId)/Owners/Owner/Id"/>

无论哪种方式，您实际上都不需要if周围的value-of，因为在没有帐户与当前帐户匹配的情况下，AccountId您将要求value-of一个空节点集，根据定义，它是空字符串。

disable-output-escaping最后，您在使用时永远不需要<xsl:output method="text"/>-在<xsl:text>&#10;</xsl:text>这里也可以正常工作。
